Rastaban

Its story

Rastaban means 'head of the dragon' in Arabic, and together with Eltanin it forms the two bright eyes crowning the circumpolar Draco, the long serpent that coils between the two Bears in the northern sky. It is a yellow G-type giant some 380 light-years away — distant enough that the light reaching this side of the sky tonight left around 1646, when Galileo had been dead only four years and his telescope was still a rarity.
