Draco (abbreviation: Dra, genitive Draconis)





The Dragon; a large constellation that coils around the north celestial pole, appearing to encircle Ursa Minor, and is one of the few star patterns to somewhat resemble the object after which it is named. The four stars forming the dragons head – Beta, Gamma, Xi, and Nu Dra – make up a conspicuous asterism known as the Lozenge. Among Draco's interesting deep-sky objects are the Cat's Eye Nebula (NGC 6543), the Draco Dwarf, and 3C 351, a quasar lying at a distance of about 7 billion light-years (magnitude 15.3; R.A. 17h, Dec. +60°). See below for details of the constellation's brightest stars.
