What is Celestial navigation?
'''Celestial navigation''' is a method of [[navigation]] where a person figures out their [[wikt:location|location]] and [[direction]] using the [[star]]s in the night sky. It has been used by sailors to help them find their way in the night. They look for familiar stars or [[constellation]]s, which will help them find their way. Celestial navigation involves comparing the [[angle]] of certain stars to other stars and how high they are above the Earth's [[horizon]]. By doing this, a person can find their [[longitude]].
