14827 Hypnos | Discovered 1986 May 5 by C. S. Shoemaker and E. M. Shoemaker at Palomar. |
Hypnos was the Greek god of sleep and twin brother of death. He entered the sleep of mortals and gave them, at the bidding of the Olympians, dreams of foolishness or inspiration, depending on the individual and their divine protectors or enemies. |
