In ancient times Polaris (the north star) was a primary source of reference to sailors in the northern hemisphere. unlike other stars that seemed to move, Polaris remained stationary in the night sky. Positioned directly above the celestial North Pole, Polaris served as a constant reliable compass and allowed sailors to determine true north. It gave the sailors stability for long distance maritime navigation and voyages across vast uncharted oceans. It also served as a celestial lighthouse and helped sailors navigate through the darkness and vastness of the ocean and come back home safely to their families who were waiting for them.
