How does the north star work?

The North Star, or Polaris, is located nearly at the celestial North Pole, making it a fixed point in the sky as other stars appear to rotate around it. It serves as a navigational reference for travelers in the Northern Hemisphere, as it indicates true north. Polaris is part of the Ursa Minor constellation and is approximately 433 light-years away from Earth. Its brightness and position have historically made it a crucial guide for navigation at sea and on land.
