Kerbol System after galaxy collision

[RA3236]

Hello,

Something that has been wondering my mind for a while is what would happen if:

• The Kerbol System was part of the Milky Way/Andromedan galaxies at the time of collision (about 200my into the future) of the two galaxies?
  
• Kerbol and the Sun became binary stars at the time of collision?
  

Thank you for those who answer my question, if this topic does not belong here tell me .

Since Galaxies are massive, but not particularly dense, I would say.... Pretty much nothing would happen. Each star system would just go their own separate lives. Except for very very few where the star systems actually interact.

Kerbol and the Sun would probably not become a binary star. They'd have to get rid of huge amounts of excess velocity, and I'm pretty sure even if they kicked out each and every one of their respective planets in gravity assists, they still wouldn't shed enough velocity.

Now IF they would come close (which is still pretty unlikely), they probably would disturb the system and cause an asteroid shower, a planet rearrangement or planets flying off into intergalactic space.

Side note: "Kerbol" is a community name. In the game, it's always "The Sun".

[RA3236]

Yeah, but where will Kerbol be after the collision?

[Kobymaru]

Yeah, but where will Kerbol be after the collision?

Collision of what?

2 Galaxies: most likely yes. Most of the Stars won't even notice it.

2 Suns: nope, that'd give a nice little super-nova. But it's also increadibly unlikely.

Kerbol is located in another universe.

It is impossible to have a star or planets with THIS ridiculous densities in our universe

Due to near-Kerbin physical laws, stars and planets have 1/10 size compared to the Solar System counterparts.

But with the same gravity, so either they have enormous density of the packed matter, or near-Kerbin gravitational constant is many times more than 6.67e-11.

That means: if these two regions with different physical laws come into close contact, the Sun collapses, the Kerbol explodes. So, we would get a nice black hole made of Sun, surrounded by a nice gaseous disk made of Kerbol.

Planets would do more or less the same.

[Hannu]

If we forget reality and think that binary system of Kerbol and Sun would be formed with magic, fate of planets would depend on geometry. If stars were close each other, even on part of their orbits, chaotic gravitational interactions would change planet systems. It would be initial value sensitive system so it is impossible to give exact results without calculation, but some of the planets would collide with each other or stars, some of them would fly out of the system and maybe some of them would find stable orbits. Probably all kerbals and humans would die without cosmic wars.

Gravitational constant of the Kerbal universe is the same as ours. You can calculate it from the standard gravitational parameter of each planetary body and its mass, both of which are shown in the map view. If the gravitational constant was different, accelerations would be different yet they are not.

It's the densities. Everything is just so enormously dense for the sake of the game because Squad thought a game where you need to wait for a long time to get into orbit would not be this popular and they're probably right.

OK, in a purely Sci-Fi universe where physics doesn't count, what would happen if Kerbol and Sol came close enough for the Humans and Kerbins to contact each other???

This scenario has already been predicted... bwaahahaaahaha

Well, galaxies coliding is not a exactly a traumatic event at star level. In fact our own galaxy exactly at this moment is colliding with the Sagittarius Dwarf Spheroidal Galaxy ...

On the very improbable case that Sol and Sun ( if I got a dime for every time that anyone uses a incorrect name for the star of the Kerbin system, I would be rich , very rich ) would become a binary system ... in spite of the absurd densities of the planets ( and star ... BTW a star so dense would most likely not be the yellow star we know from the game, but I digress ), the actual mass of the Sun system is probably 2 or 3 orders of magnitude below the one of Sol system, so unless Sol and Sun became quite close in orbit ( say, closer than the Kuiper belt ) the only diference from now would be some extra comets everytime Sun came close to Solar periapsis. If they actually got close enough ... well chaoticity would endure some planetary orbits going haywire ( like, BTW it is believed to have happened in the early Solar System due to Jupiter ). The actual results... well, if you have a supercomputer avaliable , we can actually try some simulation runs

[Brainlord Mesomorph]

Isn’t the entire Kerbal star system very tiny? The sun is like the size of Earth? And the entire system smaller than Jupiter and its moons?

So to answer the OP question, it would become another planet/but one that was on fire, with tiny moons. (And a strange parallels the 1960s America)

Our sun/star is called "Sol" (in Latin, less popular "Helios" in Greek), and KSP's sun/star is called "Kerbol". You owe me a dime.

This may fill the empty void in my life left by the demise of Futurama after season 4.

Actually the star in game is called Sun. Check the game

And I accept your dime

Jool is roughly the size of Earth and the system could barely fit inside Venusian orbit.

[RA3236]

Wow, I didn't expect a large discussion would come out like this!!! New question: if Kerbol and The Sun became a binary, what would happen to the planets?

[Vanamonde]

This looks like a question for Science Labs. And so, moved.
