How far is polaris?

Polaris is approximately 430 light years from the Sun.

Owing to its fortuitous position aligned with the north pole of the Earth, Polaris is commonly used for navigation; a sextant reading of Polaris can, with a very minor correction, be read as the latitude of a ship. However, Polaris is not especially bright; in fact, it is the dimmest star commonly used for celestial navigation.

Each light year is about 9.5 x 1012 kilometers or 5.88 × 1012 miles
