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.
