Question

How is the movement of Pole star observed

Answer 1

Polaris is very distant from Earth, and located in a position very near Earth's north celestial pole. Earth rotates once a day on its axis, an imaginary line that passes through Earth from its northpole to its south pole. ... The picture captures the apparent movement of the stars caused by Earth's rotation on its axis.

Answer 2

Look at Ursa major in the north night sky. Look at the two stars at the end of it and imagine a line joining them , extend this imaginary line to the north. This will lead you to the pole star.
The pole star remains stationery and is not a bright star
