What stars you see passing through your zenith, depends on your
latitude
on the Earth. Consider standing on
the top of the earth, the North Pole. At zenith, you will always

On the equator, then Polaris will be your furthest
northern horizon point. Stars pass over you like you were inside
a rolling barrel.
