(90377) Sedna Trans-Neptunian Object
Discovered on 14 November 2003 by Brown, M. E., Trujillo, C. A., Rabinowitz, D. L. at Palomar.
Sedna is the Inuit goddess of the sea and the mother of all sea creatures. She rewards the people of the land with food from the sea. Without her blessing, hunts fail and the people starve. She is thus one of the most important figures in Inuit legend.Naming citation (20040928/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
