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.

| 50000 Quaoar | Discovered 2002 June 4 by C. A. Trujillo and M. E. Brown at Palomar. |
| Quaoar is the great force of creation in the diverse myths of the Tongva, the indigenous people of the Los Angeles basin. Quaoar has no form or gender and dances and sings Weywot, Sky Father, into existence. Together, they create Chehooit, Earth Mother, and the trio bring Tamit, Grandfather Sun, to life. |
