Ursa Minor, the Lesser Bear, is a circumpolar constellation for observers north of 20 degrees north latitude. The constellation figure of Ursa Minor is basically the same as the Little Dipper. Its shape can be hard to pick out at a light-polluted observing location because its stars are faint, except for Polaris and Kochab, which are only second magnitude. Ursa Minor was cataloged by the Greek astronomer Ptolemy in the second century C.E. (Common Era). It is the 56th largest of today's 88 modern constellations, covering 256 square degrees of sky. | |
