To most observers the constellation of Ursa Minor is better known as the Little Dipper. In mythology Ursa Minor is Arcas, the son of Zeus and the maiden Callisto (Ursa Major). Arcas and Callisto were changed into bears and placed in the sky by Zeus in order to be protected from his jealous wife Hera. Within the constellation of Ursa Minor can be found the North Star, Polaris. By following a line from the two stars in the end of the bowl of the Big Dipper, Polaris can easily be found. The constellation of Ursa Minor is fairly dim, so a good, dark sky is needed to see all the stars. The constellation never sets below the horizon, so is visible year round for most observers in the Northern Hemisphere.
