Castor

Meaning:  (Shining, Beaver, From the Greek Καστωρ (Kastor), possibly related to κεκασμαι (kekasmai) "to shine, to excel". 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. In classical myth, along with Pollux, one of the heavenly twins immortalized in the constellation Gemini. They were considered the patron gods of seafarers, appearing to them in Saint Elmo's fire. In Greek and Roman mythology, Castor and Pollux or Polydeuces were twin brothers, together known as the Dioskouri. Their mother was Leda, but Castor was the mortal son of Tyndareus, the king of Sparta, and Pollux the divine son of Zeus, who seduced Leda in the guise of a swan. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters Helen of Troy and Clytemnestra.

In Latin the twins are also known as the Gemini or Castores. When Castor was killed, Pollux asked Zeus to let him share his own immortality with his twin to keep them together, and they were transformed into the constellation Gemini.)

This name has a decent meaning but a really cool mythological background. This is a name one could use in relevance to either the myth or the constellations and stars above. It is a nice looking name. This could also be used though in connection to Castor oil. I would love to see this a bit more but not a lot.
