We are going to collide with the Andromeda galaxy maybe 1 billion years before the sun fizzles out. Something there with opposite galactic orbit from us could smack into our sun at over 700 km/s.
as they pass through eachother, the odds are very, very low any object from andromeda hits any object in our galaxy
Absolutely! The odds are, as they say “astronomical”. That goes for all scenarios where a planet sized rock doots our sun in general.
