Interesting, I just finished reading Rendezvous With Rama.
If a massive object like that was to pass through our neighbourhood I think it could fling planets out of the solar system.
Even with this mass this planet would have to pass one of the outer planets extremely close and quite slowly to have a chance of dragging a planet out of the solar system.
This is the same sort of idea as when galaxies merge. There is little chance of our solar system being effected in that scenario. There is just too much space to space.
Aren’t we currently galaxy merging?
With Andromeda, yes
Haven't even begun colliding though. We can still see it way in the distance. It's millions/billions of years away until colliding.
Imagine the night sky far in galactic future when Andromeda is like directly overhead at night. What an amazing view. Shame earth wouldn't be around to see it.
Only a few short galactic years off!
Oh god. Thanks for that midlife crisis!
