Question

Do all the stars in sky move? Explain.

Answer 1

All the stars move but their movement is not perceptible to us. Instead of that; it is the rotation of the earth which creates an illusion of the movement of stars across the sky. But the pole star appears to be fixed at its position. This happens because the pole star is in line with the axis of the earth.

Answer 2

Answer:

No, the stars in the sky do not move. The earth rotates from west to east on its axis. Hence, all the stars in the sky (except the Pole star) appear to move from east to west. With reference to the earth, the pole star does not appear to move because it is located in the north direction above the earth's axis of rotation. It appears stationery.
