Draco constellation, its name is Latin for dragon. Draco is circumpolar (that is, never setting) for many observers in the northern hemisphere. Ursa Minor constellation, like the Great Bear, the tail of the Little Bear may also be seen as the handle of a ladle, hence the name Little Dipper. Cepheus constellation is named after Cepheus, King of Ethiopia in Greek mythology. Cassiopeia constellation is named after the vain queen Cassiopeia in Greek mythology, who boasted about her unrivaled beauty. Draco, Ursa Minor, Cepheus and Cassiopeia were all included in the 48 constellations listed by the 2nd century astronomer Ptolemy, and remain four of the 88 modern constellations defined by the International Astronomical Union. Camelopardalis is a large but faint constellation. It was introduced in 1612 (or 1613) by Petrus Plancius. Some older astronomy books give an alternative spelling of the name, Camelopardus.
