12711 Tukmit           Discovered 1991 Jan. 19 by J. E. Mueller at Palomar.
Tukmit is Father Sky in the Luiseno creation story. He was made from nothingness and together with Tomaiyavit bore the First People. The First People became all the people, animals, plants and inanimate objects of the earth, the basis of Luiseno existence.
