I don't think you could, but the more I try to think about it, the more confused I get.
I'm thinking that you couldn't because the earth would be between you and the star, but I don't remember hearing about any stars or constelations that we can't see at some point during the year. So the only possible way I can think of that you would be able to see polaris from the south pole is the same way that we can see stars that are supposed to be behind the sun, but I didn't think that earth was massive enough to produce enough gravity for that to happen. So are there stars that can only seen from the southern hemisphere,and vice versa?
Also, does the moon travel on the same path in the sky as the sun and planets?
