Polaris, also known as the 'Pole Star' or 'North Star', is arguably the most famous stellar body to hang in the western hemisphere's night sky. For centuries it has served as a vital waypoint for explorers navigating both Earth's physical oceans and the celestial starfield above.
Its apparent importance is reflected in the fact that the entire night sky appears to revolve around it. This happens because Polaris' location happens to be closely aligned with Earth's north rotational axis, which is known as the celestial pole when projected outwards into space. However, Polaris isn't the first North Star to shine down on humanity, nor will it be the last.
