what is pole star? why does it appears to be stationary? plzz give me the answer in short
Hi
Keep it up, good answering @ Singhapoorva and Saumya.
Pole star is a visible star in the constellation of Ursa Minor (also called lesser bear or Saptarshi Mandal).
Pole star does not seem to change its position because it is very near to the axis of rotation of earth. But as axis of rotation of earth is itself changing over a large period of time (called precision), thus the current polar star would be replaced by other stars in the distant future.
