Draco constellation

Draco is a large ancient constellation. In Greek legend it is usually Ladon, the dragon that guarded the golden apples in the Garden of the Hesperides and was slain by Heracles. Its long body winds between the Great and Little Bears. The head is formed by four stars, including Eltanin, the brightest in the constellation, and Rastaban. Thuban is steeped in history: around 5,000 years ago, when the great pyramids were being built in Egypt, it lay close to the north celestial pole. Other named stars include Athebyne, Altais, Aldhibah, Edasich, Giausar and Grumium. Draco holds the Cat's Eye Nebula, a well-known planetary nebula, and the Draconid meteors radiate from it in October. From Central Europe, Draco is circumpolar, and its head passes high overhead on summer evenings.
