Why do the stars appear to rotate around Polaris?
The star Polaris is almost in line with the axis of earth. So when earth rotates it does not appear to rotate in circles.
Due to rotation of earth stars around Polaris moves in circular patterns and it is visible in a long exposure photo graph of Polaris.
It is not actually the stars circle but due to earth's motion we feel like that.
