Question

A pole star is in the direction of earths axis and that is the reason why it appears stationary but earth moves and the position of earth changes and even then the pole star appears to be stationary. How is it possible?

Answer 1

Polaris, the North Star, appears stationary in the sky because it is positioned close to the line of Earth's axis projected into space. As such, it is the only bright star whose position relative to a rotating Earth does not change. All other stars appear to move opposite to the Earth's rotation beneath them...
