Polaris (pole star) is very distant from Earth and located in a position very near Earth's north celestial pole. The North Star, also known as Polaris, is known to stay fixed in our sky. It marks the location of the sky's north pole, the point around which the whole sky turns. That's why you can always use Polaris to find the direction north. Pole star appears to be fixed in one place while all other stars seem to move from east to west because it is situated in the line of the earth's axis on which earth rotates.
