The North Star or Pole Star – aka Polaris – is famous for holding nearly still in our sky while the entire northern sky moves around it. That's because it's located nearly at the north celestial pole, the point around which the entire northern sky turns. Polaris marks the way due north.

polestar, also spelled pole star, also called (Northern Hemisphere) North Star, the brightest star that appears nearest to either celestial pole at any particular time. Owing to the precession of the equinoxes, the position of each pole describes a small circle in the sky over a period of 25,772 years.
