Polaris

Definition

Polaris, also known as the North Star, is a star located nearly directly above the North Pole and serves as a crucial reference point for navigation. Its position remains relatively fixed in the night sky, making it an essential guide for travelers at sea, especially for Polynesian navigators who relied on the stars to find their way across vast ocean distances.
