Comment on A rogue object so strange, scientists aren’t sure what to call it.

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?

2-5bn years with andromeda, not even close.

Thank you but I didn’t mean andromeda. I think heard something about merging with a dwarf galaxy or something

You are correct! Here’s a really good video on the topic.

You’d think we would be able to see a dwarf galaxy approaching close to our galaxy at night? Or how dwarfey are we talking?

Our galaxy is capturing smaller galaxies but there won’t be a merge of equal sizes for a couple billion years with andromeda.

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!
