why pole star doesn't t appear to move when earth is rotating on its axis

Answer 1

Mark as Brainliest.
As such, it is the only bright star whose position relative to a rotating Earthdoes not change. All other stars appear to move opposite to the Earth's rotation beneath them. At the NorthPole, Polaris would appear directly overhead with the other stars circling around it during the course of a night.

Answer 2

because it lies on just above the earths axis. so it looks stationary
