The North Star or Pole Star, called Polaris, is located nearly at the North Pole. Some say it’s the brightest star in the sky. But Polaris ranks only 50th in brightness. The northern pole star is known by various names, including Golden Peg, Evil Star and The Star That Does Not Walk. Finding Polaris is easy. Polaris is classified as a F 7 Yellow Supergiant star, about 2,500 times brighter than the Sun. It is a triple star system, composed of the primary star, Polaris Aa (a yellow supergiant), in orbit with a smaller companion (Polaris Ab); the pair in orbit with Polaris B was discovered in August 1779 by William Herschel.
