What is the importance of the 'Pole star'?
The Pole Star, or Polaris, is directly above Earth's North Pole. From our perspective on Earth, every star in the sky pivots around the Pole Star, causing them to rise and set. Because of it's position over the North Pole, it's the only star that doesn't appear to move. It also is used to assist humans in finding north - since it's stays in the same place through out the night and year.
