This thread is dying, no one is looking at my posts!

Universe Sandbox's community is not small, but it's not big by any means either. A lack of downloads on the systems you make is not surprising. It would be helpful if you could attach a description of each system or an image to promote interest.

I agree. I love this thread but you really need to include screenshots or descriptions because there's so many.

HMMMMMMMMMMMMMMM

[Gann123]

These are the farthest Planet Systems discovered, 27,710 light years away. It's not even in our Galaxy. It's in the Andromada Galaxy. I thought it was impossible to discover a planet in anotehr galaxy but its true.

An analysis of the lightcurve of the microlensing event PA-99-N2 suggests the presence of a planet orbiting a star in the Andromeda Galaxy (2.54 ± 0.11 Mly).

Woah! And it was discovered in 2006! More Woah!
This is so woah!
You should research it yourself. Search up SWEEPS-11 or SWEEPS-4. Literally right now. No wait, download these first and look in Universe Sandbox!
The star names are so longgggggg. UHHHHHHHHHHHHHHH

If it's in the Andromeda Galaxy, its not 27,000 light years away.
It's 2 MILLION light years away.

Okay, so I just researched it and nowhere does it say its in the Andromeda Galaxy. Pretty much everything else you said was correct but it's not in the Andromeda Galaxy. Not even close.

No actually, look up list of exoplanet extremes and do to the section that says from Earth's point of view. The first one says the farthest planets are those planets. It says the quote. Maybe they mistyped or something

[Gann123]

More!
51 Peg, the first exoplanet discovered!
CoRoT-7b and CoRoT-7c, one a hot Jupiter and one a Chthonian planet!

[Gann123]

Some more!

Okay, here's my first release of the Serenity/Firefly system. I included the simulation itself, and a bunch of diagrams to visualize the system, along with a few documents on what I did and why. I intend to use this in my Serenity pen-and-paper Role Playing Game. The simulation can be moved forward to match passing of time in the game, so the Game Master can tell how long travel should take. It should be stable for at least a century, but I'm still running it to verify. It has 268 bodies that are fully attracting, so it’s a bit much to run on some computers. Please tell me what you think.

Okay, here's my first release of the Serenity/Firefly system.

That is really impressive!

Transmission Commencing...

Note: I'm not including pictures because the representations in US2 don't fit the descriptions as well as they could due to the limited amount of planet customization US2 allows. The planets are in order, so you can look at them in the sim but I'll probably post pictures of what the planets "really" look like later. The more support I get for continuing work on this system the further I'll go with it, even so far as designing maps and doing renderings of them in Terragen if you guys want. I might post this on other forums, but this is the first place I know to for sure and US2 is a really nice and easy way to get a base idea of what this system is like.

The Quiviliar System

Quiviliar

This is the center star of this system. It could be considered a typical K-type star with its main unique feature being that it doesn't reside in a binary star system as many stars do.

Ecriothea

A world with lava oceans, heavy in metals and very low in volatiles, occasionally has extremely violent eruption periods where all of the surface is covered by molten rock, eventually cooling off and forming new surface rock. At night particles in the atmosphere float down to the solid surface into a sort of "soil" in the lava plains. The plains are extremely flat and the mountains are extremely tall. It has no moons, not even small ones; the planet is much too close to its parent star to retain any satellites. Bases would be extremely hard to build here, and expensive to maintain.

Siamivira

A world of great heat, though not enough to leave much of the surface molten, and instead only having small puddles of liquid metals that have lower melting points. The planet has thick cloud layers, the top ones being composed of crystals of various ices, much like on Earth, the highest clouds are ice crystals, though these contain small amounts of elements such as ammonia as well. The main cloud layers, however, are made of mainly sulfuric acid and the atmosphere is primarily composed of carbon dioxide and carbon monoxide, the latter in notable amounts because of volcanic activity. This planet also seems to have formed with only a very small core and a very thick crust, and though the planet has a very small core, it has not cooled off and solidified yet due to the planet's mass, being 1.6374 Earth masses. The surface has very few craters; most meteors and comets of any kind burn up in the atmosphere and asteroid's collisions tend to leave no    mark because the surrounding rock becomes molten and re-covers the area. It has no moons. Bases would be difficult to build and very expensive to maintain due to the atmosphere's deadly and corrosive nature.
               
Gravatian

A world that has extremely wild temperature changes and little to no atmosphere, bathed in its parent star's heat, the daytime side can become hotter than Venus and by sunrise, the temperature often is very near absolute zero. It has a Lunar-like amount of craters, and a core to match; the planet's mass is a bit less than Mars and has long cooled and lost any magnetic field it may have had. Craters at the poles harbor small amounts of ices, mostly water, as the planet doesn't seem to have an axial tilt: it rotates at 0 degrees to its orbit. The planet's rotation is in 4:1 resonance with its orbit, possibly hinting that it is falling into being tidally locked, only being kept from it by its one moon about a tenth of the planet's size.

Gravatian I

The planet Gravatian's lone moon, surprisingly with a very thick atmosphere and extremely strong magnetosphere, perhaps allowing the atmosphere to become so thick. This magnetosphere is so strong that it protects a ring of surface material on its host planet, creating a ring of brown-colored material where the rest of the planet is mostly shades of gray. The strong magnetosphere and thick atmosphere cause the surface to be mostly covered in sand. This world possesses a sort of geological cycle where extreme winds high in the atmosphere erode mountains that grow too high, and plates that aren't pushed up by tectonic forces slowly sink down, weighed down by the immense amount of windblown sand created from the ever eroding mountainous regions. As the plates sink and the mountains grow, strong earthquakes occur along major fault zones and extreme amounts of dynamic metamorphism take place here as well; in fact, they are the main source of metamorphic rocks here, with contact metamorphism being rarer and regional metamorphism being almost nonexistent.
   
Deladreus

A dead, dusty world much like a browner version of Mars; it never had any kind of an Oxygen atmosphere and therefore rust was never able to form. It is a desert world much hotter than Mars or even Earth, with cooler temperatures more akin to the hottest days in the Sahara desert, leaving the planet inhospitable to most forms of life other than hardy bacteria that might catch a ride on a spacecraft sent here. The skies are usually a grayish brown, mostly due to the particles in the atmosphere, much like Mars' red atmosphere. There are usually no clouds unless during the occasional dust storm, which leaves the skies beyond completely obscured from the ground. Other than these things this planet is not very noteworthy and may be considered a similar planet to Mars beside highly temperature based factors such as the fact that it has no polar ice caps, and would certainly not be CO2 ice caps even if it did. The atmosphere is mostly CO2 though, laced heavily with N2 and traces of chlorine, produced by an unknown source, much like the mystery of methane on Mars.

Japusveon

This world may have once been Earthlike, but is certainly not now, for in it's current state, life could not possibly survive here. The atmosphere is choked with CO2 and massive amounts of soot and SO2 as well, among traces of many other very corrosive and toxic gasses. Chances of surviving a mission here is very low, as even spacecraft have a hard time surviving, much like how spacecraft sent to Venus in the 20th century could only function for a few hours, here those same type of spacecraft would surely only survive for a few minutes. Not only is the atmosphere extremely dangerous, it is also very thick and very high temperature, leading to many explosive chemical reactions if any occurrence happens to cause certain ones, such as the immensely explosive lightning strikes here, which cause such violent chemical reactions as to essentially be a natural bomb, to atmosphere itself detonating whenever lightning strikes, even in the dense clouds. This extreme environment was a somewhat direct result of the extremely destructive impact the planet had; it essentially went through the process Earth would go through if Ceres hit it; at first anything organic that could have been there was instantly burnt away as the initial, fastest shockwave passed over the planet, then as the object continued to collide with the planet it boiled away the water. On Earth, Ceres colliding with it would result in an H2O thick atmosphere, due to the immense amount of water here, but this planet likely only had shallow seas if not only large lakes scattered over the planet, so all of the water was not only boiled away but lost to space as well. Soon the earthquakes began, fracturing almost the entire planet's crust and liquefying much of it which was nearer to the impact, leaving the planet unrecognizable, and the chemical reactions that led to its current, deadly nature followed suit. This planet features the largest known crater on any planet, with not quite the planetary area percentage of Hershel Crater on Mimas, but, obviously, with a much larger actual size. The cater is in fact so large that the mountainous ridge around its edge is large enough to almost completely contain the atmosphere composition within and isolate it from the rest of the planet's entire atmosphere, leading this region to have a much higher SO2 content, have a much higher temperature, and it also essentially rains glass here while nowhere else on the planet.
               
Acusia

A world of mainly water, and very cold; there is land, but it is composed completely of ice, the only crust of rock being miles below the surface, the planet basically being a giant glacier, the bottom of the immense oceans being warm ice. The planet possesses a global ocean above the rock crust, this crust being very thin and only a border between the mantle and the ocean, the mantle heating the water that would otherwise surely be a high-pressure ice. Huge canyon-like cracks slowly form here due to tidal stress on the ice caused by the planet's two rather large moons.
               
Acusia I

Acusia's innermost and larger moon, about a quarter the mass of Acusia and much like Europa in the sense that it has massive cracks in the surface from tidal stress and has an internal ocean under a thick ice crust, essentially making it the opposite of Acusia, with ground on top and water underneath, rather than the water on top of an ice crust with a thin melting zone underneath that. No life is known to exist here but as the water is heated by both geothermal and tidal sources, the temperature near the solid ground not made of ice is at a reasonable temperature even when not directly near a geothermal vent so if introduced, high-pressure marine life could easily thrive here and could be used as an ark of sorts for that type of life if Terra's oceans ever evaporate enough to cause these species problems.
   
Acusia II

Unlike its host planet and sister moon, Acusia II contains almost no water content, possibly hinting at a "prograde captured" origin. In fact, it is mostly composed of what many would consider one of the things least like water: metal. In fact, Iron and Nickel, but mostly the former, seem to comprise over 90% of the entire moon's mass! Silicates do exist though, and comprise most of the other 10% of the moon's mass, leaving little room for other materials. The outer appearance is one you might expect, being much like Mercury, though without any sign of a shifting crust in it's entire history, and it also appears to have cooled off rapidly, as even though the moon is about a 6th the mass of its host planet, the boundaries of its crust are extremely vague and may not truly exist at all, as the surface contains a more moderate 80 percent metals and 20 percent silicates, but from the rare earthquakes that occur here, mostly via meteor impacts, its been shown that this composition slowly fades to a 100% metals composition in what would normally be considered the core and mantle, which in this moon's case is more like a giant though completely solid core with no definable edges. Out of the bodies in the Acusia planetary system, this is the best place to set up a base as the ground is not made from frozen water but instead the metals that can be used to create new parts of the base.

Galveon

So far, all of the planets in this star system have been rocky (Or mostly rocky...ahem...I'm looking at you, Acusia system...) but this world is the first, and yet worst example, of the end of this trend. I say this because although Galveon is indeed a gas giant of a mass between that of Jupiter and Saturn, it also contains a massive amount of metals, and may be the birthplace of Acusia II, although it is currently not known how it could have  both escaped Galveon's gravity well and migrated inward enough to be captured by Acusia. The planet has a dark, brownish-gray appearance with a slight red glow on the night side due to the metals being superheated under the immense amount of pressure the heavy atmosphere causes. It has many moons, but they are all much like Acusia II in that they are mostly of quickly-cooled metals with one exception being Galveon III which has extensive deposits of smaltite and also many of nearly pure cobalt.

Eteltos

This gas giant of great mass, 1.3 times that of Jupiter, is highly interesting, for it has such a strong magnetic field that if it were switched off, the planet may be destroyed completely; the magnetic field draws the atmospheric gas particles to them, and carries them along the field lines through space until reaching the other pole, at which time they begin migrating through the normal atmosphere to the other pole again to start the cycle again, causing a strange view of many "cloud lines" leading through space from one pole to the other. This planet is also home to the most violent lightning known, even more violent than Japusveon's explosive lightning, for this gas giant's lightning is strong because of magnetic forces, not chemical ones, meaning the lightning can be more powerful much easier. Occasionally when a moon moves over an especially lightning heavy area, sometimes the lightning can travel through the thin atmosphere the magnetosphere provides and strike the moon, although this doesn't happen often, but when it does the lightning is especially violent, leaving    a relatively large crater in the surface of the moon: this is why some of the tidally locked moons near  the planet seem to have so many more craters on the near side to the planet than the other moons have or even their other hemisphere.

Asorad

This gas giant is a teal color due to a large amount of chlorine in its atmosphere and clouds, as well as methane, and although this mixture can be explosive the mixture is kept in balance by the fact that this planet is far from its sun and has a cold interior, making for a Uranus-like appearance besides the color difference. It has many small moons, and one relatively large one, Asorad IV.

Asorad IV

This moon is a dying desert world with a reducing atmosphere of CO2 and a very large amount of dust made of an unknown material, as its chemical structure is too complex to be deduced by spectroscopy and no probe has survived long here due to a reverse-buoyancy effect the atmosphere has on any entering spacecraft, causing the one probe to land here to land just hard enough to not last long. What was discovered in this mission, however, was extremely intriguing, for there appeared to be fossils visible due to wind erosion, with the fossils being of some sort of very large spider-like creature with 12 legs in total, in 4 pairs of three.

Tunnova

This gas giant, for unknown reasons, seems to emanate immense amounts of heat; it isn't large enough to experience deuterium fusion as a brown dwarf, as it's well-known mass is only approximately twice that of Jupiter. Moons have been seen to transit the bright planet but nothing is known about them besides the fact that they contain very little ices, as they would be much brighter under their host planet's light if they contained more. Their surfaces, in fact, likely have many organic compounds on their surface, but no life likely resides here as there isn't enough solar radiation to warm the barren moons, the "tidal habitable zone" is much too thin due to this and the moons all are much too small to likely harbor life, with the largest confirmed moon being smaller than Luna.
   
Minorius 1 Alpha

The largest Kuiper-belt-esque known object in this system and the first one to be detected, likely with mostly-frozen hydrocarbons on its surface due to the white-with-black-splotches appearance it has through telescopes, as well as having little to no atmosphere based on star-obscuration measurements and the best guess of its mass is approximately the same as Mercury.
   
Minorius 1 Beta

Second to be discovered, this tiny world has the largest orbital eccentricity of any round object known, with a tilted orbit that comes as close to its host star as it can without being disrupted by Tunnova's gravitational pull, and its outer reach estimated to be over a light year away from the star it orbits! Of course, it is currently in nearly its closest pass to the star. Its mass is less than that of Pluto and it is practically a miracle it was discovered at all.
   
Minorius 1 Gamma

Third to be discovered, this object's only major known attribute is that it, for unknown reasons, has a greenish-blue hue.

Let me know what you think of this system and if I missed anything o if anything could be improved, since there's always something more to improve when trying to be realistic yet interesting. The US2 sim is attached.

[Nomad14]

My hardest achievement in this game is a galaxy with barely even a tiny fraction of stars. It is hard because of my frames but it was so worth it for the beauty, also the weird orange dot is strangely enough a brown dwarf

[Austritistanian]

Okay, I have a school project and I don't have the time to make a description for this sim, so I'm just gonna post this simulation with the summary of what the simulation is all about

The Qugyptian System

Located 450 light years away in the constellation Scorpio, the Qugyptian System is a unique binary system consisting of 10 planets, and a dozen more moons. The main star, Qugyptia A, is orbited by two planets. The secondary one, Qugyptia B, is orbited by five, one of them being habitable. The three others are gas giants orbiting far in the outer reaches of the system, and orbits both star.

THAT'S IT BYE

[Cesare]

Please can someone try to make a green gas giant.

[Austritistanian]

This thread is drowning under a swarm of spambots

[Cesare]

Has anyone discovered a solar system with 20 planets?

[Austritistanian]

No, the most ever discovered is 9 planets, HD 10180

[Physics_Hacker]

No, the most ever discovered is 9 planets, HD 10180

They might mean made a system with 20...I probably could make a reasonable system with 20 planets (Maybe a binary or, even easier, a trinary system?)

[Cesare]

The good thing is that in Universe Sandbox 2, you can make solar systems with as little or as many planets as you want. You can even create binary planets and create moons for planets as well.

[Austritistanian]

Well, why didn't you ask "Has anyone made a solar system with 20 planets?"?

[Cesare]

You could make a solar system with 20 planets and upload a simulation video here.

Alkypso and Dretuclite

Alkypso and Dretuclite is a binary star system consisting of a hot, young and massive O-type star named Alkypso and a small, old, ultra-cool M-type red dwarf named Dretuclite. Containing a total of 13 planets, a total of 15 moons (excluding asteroid moons), and 9 comets.

Both Alkypso and Dretuclite used to be single star systems. Dretuclite formed 2.5 billion years before Alkypso from a completely different cloud of gas. That changed when Dretuclite passed within a single light year from Alkypso, causing it to be captured by Alkypso's gravity. Dretuclite's gravity also perturbs the cloud of icy planetesimals surrounding Alkypso, sending a swarm of thousands of comets bombarding the inner planets, similar in some way to our solar system's Late Heavy Bombardment.

Alkypso

Alkypso is a young, hot, and extremely massive O-type star, at 8.2 solar mass. It already lost a few percent of its mass, and is about to go supernova within 10 million years.

Hermine
Hermine is the first planet of the Alkypso system. It is a super-earth planet roughly 4.5x the mass of Earth. The planet's mountains are covered in purple-ish sand-like particles, it is unknown what causes this purple color. Overall, most of the terrains are flat with little to no surface features. Average temperature is 450°C, and because the planet has no atmosphere, the day side can become hotter than Mercury, while the dark side could go as low as -95°C.

Knurgil
Knurgil is the second planet of the system. It is a super-earth planet 8.3x the mass of Earth. The planet is distinctly white, and has a high albedo of 0.45. It has an extremely fast rotation speed of 3.4 km/s, meaning that a day in Knurgil is just 5 hours and 58 minutes. This also means that, despite the planet having no atmosphere, the temperature difference between the day side and the night side is just 125°C, from 350°C to 225°C.

Alure
Knurgil's only natural satellite, nearly three times the mass of Luna. Like all moons, it is tidally locked, meaning that one side is always facing the planet while the other side is always facing away. The longer day (at 8.21 days) means that the temperature difference is greater than on Knurgil. The day side can get as hot as 510°C while the night side can get as cold as -102°C

Mikypsia
The largest rocky planet in the system, at 10x the mass of Earth, and the only planet with a visible ring system. The planet is ominously dark, with a low albedo, a thick atmosphere, and a surface temperature of 502°C. The thick atmosphere, over twice as thick as earth's, makes it better at distributing the star's heat than earth, this means that the night side would only be a few degrees colder than the day side. Clouds do exist in the planet's atmosphere, but instead of made out of water vapor, it's made out of aluminium and glass, and when it falls down, it literally rains glass.

Wharvis
One of Mikypsia's three moons. It is 2.85x heavier than Luna. It somehow resembled Saturn’s moon Iapetus, with the brown and white landscape. The moon has an unusually large iron core, which gives the moon a high density.

Fienus
Mikypsia’s second moon. It is 2.57x heavier than Luna. The moon is distinctly blue in color, and it is unknown what causes this blue color. One of the weirdest feature this moon has is that just under 16°N it has this long, really thin mountain range that runs almost perpendicular to the latitude line. Some theories suggest that it’s an inactive reverse fault line.

Manescu
Manescu is the furthest moon of Mikypsia. It is 2.12x heavier than Luna, slightly heavier than Jupiter’s Ganymede. It orbits 1.91° below the actual orbital plane of the other two moons. The moon’s surface is distinctly orange, with blue on the highlands. The terrain is very rugged, with extreme cliffs and steep hills. The southern plateau covers an area a little over half as wide as the contiguous United States, and it has some of the most extreme terrains in the moon, with insane cliffs that are comparable to Mars’ Valles Marineris, which isn’t even a near 90° cliff.

Dhirbekk
Dhirbekk is a gas giant exactly half the mass of Jupiter, and almost exactly 200000 km wide, which is wider than Jupiter, suggesting that it’s a very low density planet. The planet’s atmosphere, which is mainly composed of ammonia, nitrogen, and argon, is divided into five belts: the south pole, the orange belt, the equatorial belt, the blue belt, and the north pole. The south pole surrounds the south pole, and is mostly blue-ish white. The orange belt is, as the name suggests, orange in color, and mainly surrounds the southern mid-latitude. The equatorial belt is a mix of orange color and blue color, with a little bit of white. The blue belt is, well, I don’t need to explain it to you, and mainly surrounds the northern mid-latitude. The north pole surrounds the north pole and is distinctly greenish yellow in color.

Roefnor
Roefnor, Dhirbekk’s only major moon, is often called “Mars’ darker cousin”, this is mainly because of it’s dark red color, almost as if it was tanned. Roefnor is situated on the edge of Dhirbekk’s Van Allen belt, which subjects the moon into huge amounts of radiation. Average temperature is 140°C

Gnizgerv
Gnizgerv is the most massive planet in the whole system, at 3.23x the mass of Jupiter. Gnizgerv is separated from Dhirbekk by a grand distance of 71 AU, you could comfortably fit the entire solar system within it, and there’s still room for Pluto. What’s really weird about Gnizgerv is that it rotates on the opposite direction, and it’s not a slow rotation either like Venus, this planet rotates once every 7 hours and 39 minutes. The magnetic poles are also inverted, with the south being north and the north being south, and the magnetic field extremely powerful, at 18.5 gauss, nearly twice as powerful as Jupiter’s magnetic field. This also means that the Van Allen belt extends much further than Jupiter. Another odd thing is that this planet hosts two planetary mass moons, and they’re not small either, one of them is 3.5x heavier than Earth, that’s larger than all of the rocky planets in the Dretuclite system. This, along with the fast rotation and the retrograde rotation, baffles scientists and astronomers.

Pruhetania
Pruhetania, Gnizgerv’s innermost major moon, has an extremely rugged terrain. While most of the mountains are not that high, the steep hills and extreme elevation differences makes for a world that is barely navigable. Dry riverbeds can be seen across the surface, it’s unclear whether Pruhetania used to have liquid water on its surface.

Sciron
An cold world covered in ice, Sciron is similar in many ways to Jupiter’s Europa. While having a surface temperature of -108°C, liquid water could exist under the surface thanks to geothermal activities, which could host multicellular lifeforms under its surface.

Drevdiak
Drevdiak came so close to being Earth-like, with liquid water, land, and an atmopshere, but due to the fact that the moon is still in its adolescence (at least, compared to Earth), it wouldn’t be for another one billion year until life resembling that of the Earth to develop, as right now the landmasses are just boring rock and sand and the ocean only has microbes, and Alkypso would’ve already went supernova long before that. The earliest life forms on earth lived 250 million years after Earth had formed, and considering that the whole system (excluding Dretuclite) is just under 32 million years, y- you already know my point.

Vardekk
Vardekk, at just under half the mass of Luna, has an unusually high density, it’s denser than all the other moons, denser than even Alex Jones. One theory suggests that Vardekk might have collided with another moon in the past, ejecting away its outer layers and leaving the mantle and core behind.

Stoetzel
Stoetzel, at 1.81x the mass of Luna, is very similar to Sciron, with a subsurface ocean under its ice that might host multicellular lifeforms. Interestingly, the ice layers acts like a crust, and has tectonic plates, meaning that earthquakes are frequent in this moon.

Ashkyk
Ashkyk stands out from the rest of the moons in the system as it is extremely huge, not 10x the mass of Luna, not 50 either, but 288x the mass of Luna, roughly 3.5x the mass of Earth. That, along with Anaetua accounts for 99.91% of the total mass of the entire Gnizgervian moon system. It is yet unknown how Ashkyk grows to become so huge, but with that kind of size comes some very interesting stuff (that’s what she said). Ashkyk is covered in liquid water, and has an earth-like atmosphere, key feature for life to develop. Life actually developed quite early in this moon, much earlier than Earth, several small marine creatures can be found swimming in the 800 km deep ocean. However, due to Gnizgerv’s tidal force, the moon is in a 1:2 rotation-orbit resonance, meaning that a day in here is over 78.5 days long, and continues to slow down. Moreover, the long rotation period causes the temperature difference between the day side and the night side to be much greater, even with an atmosphere. This means that at noon, the ocean temperature could get as high as 42°C, which could generate severe thunderstorms and hurricanes.

Zack
Zack is a moon, orbiting around Ashkyk, which is also a moon. This submoon is actually pretty heavy, at 0.6x the mass of Luna, larger than Vardekk. It is likely that Zack used to orbit Gnizgerv before being captured by Ashkyk’s gravity.

Anaetua
This weird gas giant planet which keeps hammering astronomers with questions not only hosts one planetary-mass moon, but two. This one is a lot smaller, at 1.23x the mass of the Earth, and unlike Ashkyk, it has no life. But it does have two moons, Yortuon and Themysca, both of them are asteroids.

Dretuclite

Dretuclite is an old, ultra-cool red dwarf roughly 81.7x the mass of Jupiter, or 0.078x the mass of Sol. It's so dim that it'll be indistinguishable from any other stars in the night sky as seen from the Alkypso system, while Alkypso itself would appear as bright as a full moon as seen from the Dretuclite system, and 10x as bright during closest approach. The star also orbits in a retrograde motion, at least from Alkypso's perspective. The planetary system is made up of 8 planets, with two being habitable. The star is also orbited by asteroids captured from the cloud of icy asteroids surrounding Alkypso

Yustrippe
Yustrippe is the innermost planet of the Dretuclite system, it is 8.34x the mass of Luna, about as heavy as Mars, but a lot denser. Its surface is a lot like the Moon, almost entirely gray. Like nearly all planets orbiting around a red dwarf, it is tidally locked, meaning that one side is always facing the star while the other side is always facing away. The day side can get as hot as 310°C while the night side is always under -210°C.

Azgarr
Azgarr is the second planet of the Dretuclite system. It is 25.4x the mass of Luna, and has orange mountains with blue lowlands. This planet has not much to offer, like all the other planets, it is tidally locked, and it has no life.

Dhekmul
Dhekmul is third planet of the system with a 10.8x the mass of Luna. The planet is a lot denser than all the other planet in the system, at 6.2 g/cm³.  The terrain is pretty flat, with the highest point reaching 3200 m up.

Thegrun
Thegrun is a Venus-sized desert planet with an earth-like atmosphere, several liquid water lakes and a diverse amount of species. The whole planet is essentially a large desert with very few vegetation. Large lakes can be seen, most of them are larger than the Caspian sea. Thousands of different species can be found around the terminator line, the line that divides between day and night, where the temperature is just right. However, because there are very few plants scattered across the planet, most of the species are carnivorous.

Xigleion
Xigleion is a water world planet 52x the mass of Luna. This planet has an extremely diverse marine ecosystem with hundreds of thousands of marine creatures, from near the surface to the very bottom of the thousand-mile deep ocean, from small microorganisms to monstrous aquatic creatures. The far side is all covered in ice, and has all types of creatures walking among the frozen land.

Craunides
A large, cold and icy planet 2.13x the mass of Earth, the most massive of the Dretuclite system. Craunides has an extremely high albedo of 0.82, so even the bulls-eye remains well below 0°C. It has an incredibly thin atmosphere similar to Pluto's atmosphere, and it's mostly made up of ammonia and nitrogen. Like Europa, it likely has a subsurface ocean where multicellular life could develop.

Darg
Darg is a cold, barren planet with 1.65x the mass of Earth. The average surface temperature is -146°C, the bulls eye being -11°C, and the far side being -243°C. Despite being the farthest planet in the system, it is still tidally locked.

I used this website to generate the planet names. However, some planets and moons are given names by myself
