About a third of the way from Dubhe (the Big Dipper’s front bowl star) to Polaris (and a just a bit to the east) lies Giausar, the tail star of Western Draco the Dragon, to which Bayer assigned the Greek letter Lambda. Draco (constellation) (Wikipedia) Draco is a constellation in the far northern sky. Its name is Latin for dragon. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today. The north pole of the ecliptic is in Draco. Draco is circumpolar from northern latitudes. There it is never setting and therefore can be seen all year.

Legend has it that this is the dragon slain by Heracles during one of his labours, and in the sky the dragon is depicted with one foot of Heracles (in the form of the neighbouring constellation Hercules) planted firmly upon its head. This dragon, named Ladon, guarded the precious tree on which grew the golden apples. Thuban for the first time
