regarding GP2

[FCDetonados]

we know that there is going to a second gas planet, but i think it would be way to awesome to have a binary sistem of 2 gas planets with like 7 moons,

also it would be perfect to test the [barycenters](http://forum.kerbalspaceprogram.com/threads/39620-Barycenters-and-non-spherical-Volumes-of-Influence-(an-idea-for-binary-planets-stars))

[LethalDose]

Binary planet systems have been recommended elsewhere, but would require n-body gravitational physics, which are on the do-not-suggest list.

I'd expect this to get locked shortly.

[vetrox]

before this gets locked.

Could you not just have an invisible barycenter and have the two gas giants orbiting that? Although im not sure if you can then have moons on each of the gas giants

[astropapi1]

Binary systems are a no-no.

No. If you ever enter that point, the kraken will devour your game

[Unfawkable]

Why is this so bashed upon, is it REALLY that impossible to code? It looks like a pretty cool idea, no matter how many times it was suggested.

[FCDetonados]

ok its not a binary system anymore both gas giants are orbiting the kraken

[Chrisd857]

For a proper binary system, no reasonable algorithm or model has been proposed other than some form of numeric integration on at least 2 bodies (2...n-body).

So, bye-bye the current patched conics system, with its on-rails orbits and all that. It isn't hard to code, but it might be slow to run, and it might not be as fun.

[Deadpangod3]

Why wold it be impossible for moons for these binary giants? If their orbiting an invisible barycenter, like a moon,

Wouldn't it be as simple a coding another moon in?

Krags planet factory has a moon orbiting a moon, so it must not be impossible

[Kasuha]

Impossible to code? No

Incompatible with current game implementation? Yes

[vexx32]

Yeah, not possible. The SOI system KSP uses means that any kind of barycenter would have to be a singularity of gravity, and passing through the barycenter in that kind of implementation would simply fling you out at superluminal velocities, much like the Sun used to in earlier versions of KSP.

[FCDetonados]

ok i made sketch using paint(and yes i suck at paint)

imagine that everything is orbiting the barycenter(just until we actually have n-body physics here on ksp)

[FCDetonados]

Yeah, not possible. The SOI system KSP uses means that any kind of barycenter would have to be a singularity of gravity, and passing through the barycenter in that kind of implementation would simply fling you out at superluminal velocities, much like the Sun used to in earlier versions of KSP.

something just came to my head

why not put a moon on the barycenter?them that singularity problem would be fixed

[chaos_forge]

the Barycenters thread that OP linked to has already covered all of this, and concluded that it would in fact be possible to do with a patched conics system. If you're interested in the topic, at least skim through that thread so we don't have the same argument all over again. (Sorry for the shameless self-promotion)

[Unfawkable]

Well that sucks. Maybe it'll get fixed one day

How does orbiting a black hole instead sounds? Like, a mini black hole. Would add even more to the exploration part, and would justify why you'd get destroyed if you come too close.

[chaos_forge]

-sigh-. What do people on forums have against reading?

As we concluded on the Barycenters thread, the best approach would be to modify the SOI logic to be able to have non-spherical SOI's, allowing you can bypass the problem with a configuration something like this:

If you want to talk about the barycenters, please go to that thread. Actually, it'd be better to start a new one to prevent necro-posting.
