The Pole Star/ The North Star





The North star is on the handle of the Little Dipper . The Little Dipper is also known as the Little Bear and URSA MINOR. Use the Two stars on the Big Dipper (also known as The Big Bear, URSA MAJOR) as pointers to the North Star. The name of the North Star is called Polaris. Polaris is in a group of stars called Cepheids which are in a later stage of their life and so pulsate in intensity . In 2010, Astronomers have recently seen Polaris brighten up after 100 years of seeing it fading away . This is the only star that appears stationary as all other stars appear to revolve around it. It is used for land/sea/air navigation.
