Polaris, so named for its position directly over the North Pole is a special star.
Yes, you can measure your exact latitude by simply measuring the angle between the horizon and the Star, and you can use it to identify North without the aid of a compass, but it has one interesting attribute in the night sky.
It is stationary.
All the stars in the night sky revolve around the North Star. Constellations will change sides in the sky or rotate to be entirely upsidown, but the North Star remains a fixed beacon of truth in the darkness of night.
