The north star, also known as Polaris, is special because it is located at the northern axis of the Earth. The star's position in the sky is constant therefore, it has been a useful navigational tool since ancient times.
Its brightness and fixed position of North Star Polaris makes it special. The North Star is located near the north pole and it looks so bright in the north. Being at the north pole it does not move with the passage of time and thus, it is used as a reference for finding the direction during sailing and other navigations.
