Looking at the video, yes. But not in the form of something colliding with the Sun. I would guess the most likely interaction would be perturbations of orbits as the solar system deals with these freight trains going by. That could result in anything from planets changing orbits as they follow the changes in the Sun's orbit around the galactic center, to having the entire solar system ejected on its own path away from the galaxy (that first pass "collision" is going to impart a lot of momentum on different systems. It shows a 'spray' of things going out from the galaxy but those things are stars with their nominally attached planetary bodies!)
- jessriedel 7y agoThe planetary orbits in the solar system are vastly smaller than the typical distance between stars in the combined Milky-Way-Andromeda system. The only difference will be a slightly higher typical speed for Andromeda stars compared to the relative motion of stars in the Milky Way disk. But that's only by like a factor of 10, and I don't have any reason to think that will cause a perturbation that's noticeable above the normal uncertainty from chaos in planetary orbits.
