Re: Yes..

Well, the Galaxy is huge and the Sun hasn't turned around its center that many times, indeed.
But look at the other aspect: our nearest star neighbour (other than the Sun) is 4 lightyears away, while Mars is sometimes 60 million km away. But if you take the size of our Galaxy, M31 (Andromeda) is about 29 times further than our Galaxy's size. (not much); kind of like our Moon being 30 times further than Earth's diameter.
