Question
Explain the factors which differentiate the pole star from other stars.
✓

Answer

Pole star is like any other star. But the only difference between pole star and any other star is that the pole star lies on the axis of rotation of the Earth so it remains fixed at its position with respect to the position of the Earth whereas other stars appear to be moving with respect to the Earth. The brightest pole star is Polaris lying above the earth’s North Pole.
