Diffinio Castor
From the Greek name Καστωρ (Kastor), possibly related to κεκασμαι (kekasmai) meaning "to excel, to shine" (pluperfect κεκαστο). In Greek myth Castor was a son of Zeus and the twin brother of Pollux. The constellation Gemini, which represents the two brothers, contains a star by this name.
