    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.

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

        Yes we are in middle of a multi million year process of merging of the bigger Andromeda galaxy and our Milky Way galaxy.

          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.
