For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

| 90377 Sedna | Discovered 2003 Nov. 14 by M. E. Brown, C. A. Trujillo and D. Rabinowitz 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. |
