You're assuming the Moon is traveling toward that specific system...

It's going in a random direction, and probably in a straight line.

Statistically, even at light speed, they would probably only encounter another system every few millions of years or so.

you are right of course.

i am assuming the most optimistic outcome that is physically possible, no matter how unrealistic. because if we go by statistics we'd have to scrap most movies that are about an unrealistic (but possible) event.
