Yeah, in the Epsilona Revoluta system, Revanobl keeps on getting tugged from a .29 Eccentric orbit to a .029 Eccentric orbit by Revoluta and Resisica Etani. Resisica Etani is 6.85 times the mass of earth, so that might be the problem. Resisica Etani and Revoluta are both in the habitable zone of Epsilona Revoluta, while Revanobl has a 25 M Km SMA.

I think I'll write an accretion disk guide.

Denisine wrote a pretty good description of it. Although I've made a few tweaks to the adding kms for things lower than 900 km. I'm going to fine tune it somewhat though since I had origionally adapted it to the fact that I had so many low diameter objects in the binary and the mass was split between the two.

So I started mine around a binary pair.

When finished, the pair will be separated by about 186 M KM.

B has lots of planets on the plane of ecliptic.

A is jut a mess

The largest body in the system is approx 8.00 Moon masses.

How closely separated are they right now? In the Centauri system right now, the closest approach is 1.16 AU (about 173.53 M km), which is a little closer than the distance yours will be when you put the system to solar size.

The binary is almost circular, right now they are about 18 M km away from eachother.

Literally every minute several objects switch stars.

Expect that to happen ALOT, especially as the objects increase in mass. It'll slow down a little over time as things get ejected. Also, watch out for wrecking ball gas giants, they'll probably get ejected, but before that, they'll try to wreak havoc.

Anyways, the Centauri system passed the thousand year mark. Of the 17 named objects (all objects over 900 km), five of them are in the earth mass range. Translated into Jupiter masses, they range from 44 to 79 Earths, basically small Saturns and they're still growing. One is at 6.30 moon mass and another is at 4.19 moons, not sure if that would eventually make them small Neptunes or Super Earths. The rest of the named objects range from 0.53 to 0.080 moon masses. There are 67 planets/planetoids total, not counting the designated stars of course.

I just did a census and now we are down to 251 objects.

No, wait, make that 249. Two got ejecte- now it's 248.

Things are getting slingshotted out at 75 km/s!

EDIT: OMG SOMETHING GOT SLINGSHOTTED OUT AT 348 KM/S!

17 Years, and 80 objects.

Woah, wth.

smjjames · « **Reply #99 on:** December 20, 2011, 06:11:27 PM »

Since your stars orbit so close to each other, the ejections are probably happening MUCH faster. It took a little longer for me, but every time the two stars get close to each other, alot of objects would either get ejected or kicked to a higher orbit.

It still happens even now, every time they get close to each other, either an object or two will exchange stars and one or two objects will get flung out or put it on a path that would get it flung out.

Your cameras FOV seems a bit high in that screenshot, otherwise, neat screenshot.

An update on the Centauri system, it has passed the 2200 year mark and the system shows little sign of stabilizing back up. It was actually a really stable system until two gas giants flipped stars and started really messing things up. Later, one of the two got flung out, but the other wrecking ball of a gas giant is still around and also happens to be the largest in the system (it's now at 0.41 earths). I think the main problem is that I ended up with too many gas giants, six total now with one that is at about 8 Earth masses, not sure if that makes it a mini Neptune or a Super Earth. Not to mention the orbital dynamics involved with a binary.

In short, the system used to be stable and now it looks like a mess. I have 55 objects, not including the stars, so I hope some more stuff gets ejected during the next 800 years of sim time so I don't run out of letters, heh. Also, I was thinking of running it further after the 3000 year mark as it is to check for stability, but decided that the stability would be better tested in full scale.

Also, is there an easy way of getting a whole load of orbital information into Excel?

vh · « **Reply #102 on:** December 21, 2011, 04:43:58 PM »

maybe copy paste it from xml file? no idea.

smjjames · « **Reply #103 on:** December 23, 2011, 09:12:20 AM »

As far as moving the XML stuff to Excel, apparently the orbital data isn't in the XML, thought it would be.

Anyways, I've finished the Centauri System accretion. I thought I could maybe let it run for another thousand years of sim time to see if anything will stabilize into the habitable zones. Unfortunately, while plenty of objects go through the habitable zones, none of them stay within it. The system was actually stable for a long time until wrecking ball gas giants got swung around. The one main marauding gas giant got flung out near the end, so YAY for that

Also, for some reason, Centauri B's orbit got shrunk when I moved it outwards and made the system a binary.

Heres screenshots of it and a save for you guys to check out.

You don't need to bump it unless you have a new system to share.

But wouldn't a bunch of other people with systems to share want a place to share them?

Could you upload the last three images to the thread? They're thumbnail size for some reason. Go to additional options to do that.

Spaceguy888 · « **Reply #109 on:** February 12, 2012, 01:48:41 PM »

the size of my last ones were messed up so I gave up editing them and made some new ones.

two of them are not really exoplanets but are actually altered planets.

smjjames · « **Reply #110 on:** February 12, 2012, 01:53:56 PM »

lol on the name of the second one. Also, don't the landing spots mess up the orbits? I've heard of the bug involving those where they act like a thruster stuck into the side of the object.

You have to give it a mass larger then the object it is on.

I WORKED FOREVER ON THIS SYSTEM!!!!!!!!!!!!!!!!!!!! and here are the planets
a gas giant larger than jupiter

a planet with water vapor atmosphere
an earthlike planet the size of mars
an roasting hot planet

cool, did you make the textures yourself? maybe we could see the system with all the planets in orbit

Europa64 · « **Reply #116 on:** April 06, 2012, 09:42:41 AM »

Yes i made them myself with programs that make planet textures and here are pictures of all of them in orbit well not all since the system is so big i have to make one picture or inner planets in orbit
another in outer planets

And a pic of the central star in comparision to the sun
