Background & History
As a star, Polaris does not have a founding or organizational history.

This position has made it a constant reference point in celestial navigation and various cultural mythologies.
Why Notable
Polaris is notable for being the current northern pole star, meaning its position in the sky is very close to the north celestial pole. This makes it appear nearly stationary, providing a reliable fixed point for navigation in the Northern Hemisphere. Its brightness and unique position have cemented its importance in astronomy, navigation, and human culture throughout history.
In the News
Polaris remains astronomically relevant as its precise position and characteristics are studied by scientists. It is a well-known Cepheid variable star, used for measuring cosmic distances. Its role as the North Star continues in basic celestial navigation and stargazing education.
