79360 Sila-Nunam           Discovered 1997 Feb. 3 by J. X. Luu, D. C. Jewitt, C. A. Trujillo and J. Chen at Mauna Kea.
Sila is the Inuit god of the sky, weather, and life force. Nunam is the Earth goddess, Sila's wife. Nunam created the land animals and, in some traditions, the Inuit people (in other traditions Sila created the first people out of wet sand). Sila breathed life into the Inuit.
