Antilla System

Sorry for my inactivity, I've been working on a system for the past week. This is what I've been working on, the Antilla system, a solar system with 12 planets

I'm trying to take advantage of the recent hyperbolic update to make this new simulation, it's more of a story-based simulation, and I wanna know what you guys think about this.

Kameahele

The year is 2123, a large swarm of comets enters the inner solar system, with several close encounters with Earth, and some others hitting planets like Jupiter and Mars. While the bombardment is not as intense as the Late Heavy Bombardment, astronomers are sure that there is something in the outer reaches of the solar system that is responsible for this event. Upon researching, they found a bone-chilling discovery.

A massive planet, over six and a half times more massive than Jupiter and nearly 2.3 times its diameter, is found to be moving at an incredible high speed directly into the inner solar system. This marks an incredible discovery in astronomy, as it is the first known planetary-sized interstellar object to pass through the solar system, and the second known interstellar object to pass through since Oumuamua back in 2017.

The planet, dubbed "Kameahele" meaning "wanderer", appeared to be coming from the constellation Scorpius, more specifically the star V1003 Sco, at roughly 17.2 km/s. Astronomers calculated that the planet will reach periastron (closest point to the Sun) on October 21st, 2269, at a distance of 3.8 AU, and would also appear in the constellation Ursa Major as viewed from Earth. It will appear 4x brighter than Jupiter, and would be so close that it would be visible to the naked eye with no telescope required.

Upon researching Kameahele's trajectory, they found that the planet will fly past Uranus at an extremely close distance of 95.4 million km. This would strip away some of the moons of Uranus and would slow down Uranus pushing it into a closer, more eccentric orbit.

Kameahele will move away from the solar system and back into interstellar space, roughly towards the constellation Cetus.


Kameahele at a distance of 21.5 AU


Kameahele during periastron, at a distance of 3.8 AU


Due to close encounter with Kameahele, Uranus fell into a more eccentric orbit

How can I create an empty .ubox file to create a planet from scratch?

I guess ... in the main menu, select the "Open" category, check the box to open all simulations in pause mode, return to the main menu (left arrow at the top), then click "New", set your preferred background, and save it.



I created a kind of "benchmark system" by putting a large star (Polaris, ≈4.5 M) with a high spin  into a quite excentric elliptical orbit of about 20d around a black hole with 1 Mio. M.

Approaching the periapsis, Polaris gets partially torn apart and emits dozens of fragments. After 20, 40, and 60 days, each close to the apoapsis, I select all fragments inside the orbit and convert them to full bodies, the escapees get deleted (would vanish after a while anyway).

So I saved each result to continue some benchmark tests regarding the simulation speed limiter. Here I noticed that a saved and reloaded simulation behaves slightly different to the original continued one. But that's not the point yet. The real surprise was that I seem to reach accuracy limits, leading to different results after the simulation continues for a while.

At higher speeds (3..6 h/s), the remains of the star (only 111 jupiter masses left) usually just burned out. But running at a slower speed (30 min/s), after one last collapse to 99 Mj, it went off into a supernova?! :o How is this possible with so little mass left? I'm not complaining about a "bug" here, I'm just curious about possible reasons. Maybe the high spin is an important factor.

The secondary star. It was once a big, happy star, but now its slowly being eaten by the vampire star... It will vanish a few million years from now. :'(

Is it just the camera angle or is it already ellipsoidal? ??? I'll have to test that one. 8)



No, just the camera. SpaceEngine can display tidal stars, skewed by gravity and spin.

Does anyone know how to add barycenter to binary stars?

Select both (e.g. with Ctrl+LMB rect); click one in the selection at the right screen border; click "Create barycenter".

This is the earth at 1500 degrees Celsius (3000 degrees Fahrenheit) I will give more links similar to this, but for now the description is:
"1,500C is the temperature of a furnace. Heat the Earth
to this temperature, and it will melt anything living,
then slowly begin to cool as its heat is lost into space."
It slowly cools to 1499, 1498, and stays still at 1400 or so, and cools down over thousands of years to absolute zero. Universe Sandbox has 500, 1000, 2500, 5000, 10000, 20000, 50000, 100000, and 1000000 degree Earth, but there's a 1,500 degree version for it. There is a picture of the 1500-degree earth, and that's how it looks at the start of the simulation.  The first row below this 1500 degree earth photo shows the image upload link, and the second row shows the simulation download link.

There are many stars colliding in this simulation. It makes a super violent supernova, call it a hypernova instead. Hypernovae are super violent supernovae.

I also have a 2000-Celsius-degree-earth-link, and I have a photo of it. The description is:
"2,000C is colder than the temperature of 2MASS
J0523-1403, one of the coldest known
stars in the universe. Heat the Earth to this temperature,
and it will melt anything living, then slowly begin to cool
as its heat is lost into space." The first row below this 2000 degree earth photo shows the image upload link, and the second row shows the simulation download link.

AGAIN I made a 3000-degree celsius (6000-degree fahrenheit) earth for you. I'm just saying AGAIN capital because I'm happy of the earth-series. The description is:
"3,000C is roughly as hot as the surface of Proxima
Centauri, the nearest star to the earth beside the Sun. Heat
the Earth to this temperature, and it will melt completely,
then slowly begin to cool as its heat is lost into space." The first row below this 3000 degree earth photo shows the image upload link, and the second row shows the simulation download link.

MAYBE I have a 3500-degree celsius (7000-degree fahrenheit) earth for you. The description is:
"3,500C is roughly as hot as the surface of the Sun when it
becomes a red giant in 5 billion years. Heat the Earth to this
temperature, and it will melt completely, then slowly begin
to cool as its heat is lost into space." The first row below this 3500 degree earth photo shows the image upload link, and the second row shows the simulation download link.

I ALSO have a 4000-degree celsius (8000-degree fahrenheit) earth for you. The description is:
"4,000C is roughly as hot as the surface of the Sun when it
becomes an orange subgiant in 4 billion years. Heat the Earth
to this temperature, and it will melt completely, then
slowly begin to cool as its heat is lost into space." The first row below this 4000 degree earth photo shows the image upload link, and the second row shows the simulation download link.

I made the Sun yellow-white instead of yellow. It got 1000 degrees celsius (2000 degrees fahrenheit) hotter, but still it would be a great simulation to explore.

Oh my ice cream! The Sun turned orange and Earth became a snowball, so Antarctica would be -100 to -200 degrees fahrenheit. Even though Venus was still in the habitable zone, it was 500 degrees because of that clouds.

Give me all the snow! (Just saying) I made the sun 3500 degrees celsius like a red dwarf and it made almost every planet cold except venus!

The Sun is 2000 Degrees Celsius! It is a extremely freezing solar system, so download it.

The Sun is just a Brown Dwarf, which would make the whole solar system frozen. The planets are now like moons.

The Sun is only 500 Degrees Fahrenheit! The other day I touched that heat (not even that hot, I mean twice as less, which is 250), then I got a 1st degree burn. Never touch 500 degrees, you could get an extreme 2nd degree burn or a mild 3rd degree burn. But for now 500 degrees are too cold for a star. Here's a link for this dark-brown dwarf.

The Sun at absolute zero freezes the solar system instead of burning. It's so cool to see planets freeze! (I had the idea of the sun at different temperatures).

I have a white sun. That means it is like more than 15000 degrees Fahrenheit. It makes the Earth as hot as a broiler oven at 500 degrees. It even burns Mars!

I have this blue sun that makes the Earth more than 1000 degrees. Like mild lava. But it can burn Jupiter and Saturn to 150 degrees! (I mean Fahrenheit)

A 100000-degree sun shall sacrifice a molten earth..........................
We have a 100000-degree sun making the Earth hotter than lava. It is beautiful blue, but nobody wants to see this in real life!

This is the hottest sun at more than 178000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 degrees Celsius!!!!!!!! That's not infinity, but it will say. Also, US2 should make it up to 9.99E+999. But that sun melts all planets and even itself and only frigid asteroids survive the melting.
