[mrjesse] Are you saying that when I look up at the night sky half the stars I see are actually on the other side of the world?

[LeGrande] They might be. They have had billions of years to move around.

Sirius is 8.6 light-years away. Is there some reason why Sirius should move into the Southern hemisphere in only 8.6 years?

Sirius is close to us so its actual position is going to be very close to its apparent position. Why do you think that it would move into the Southern Hemisphere?
