Named for a son of the sage Kasyapa and Vinata {see planet  (2347)} in the mythology of India. Vinata laid two eggs. When after five hundred years neither had hatched, she broke one open to find Aruna with only his upper half developed. He went into the sky to become the red glow of dawn, where ever since he has driven the suns’s chariot each morning. (M 21605) _ _.
