#nu centauri

Centaurus, the Centaur, is a southern constellation and one of the original 48 that Greek astronomer Ptolemy set down. Centaurus has long been seen as a half-man, half-beast as early as the Babylonians who saw it as the Bison-man.

According to Ovid, Centaurus represents the centaur Chiron, who was a tutor to Heracles, Theseus, and Jason (leader of the Argonauts). He was put into the heavens after accidentally being hit with a poison arrow show by Heracles.
