136472 Makemake           Discovered 2005 Mar. 31 by M. E. Brown, C. A. Trujillo and D. L. Rabinowitz at Palomar.
Makemake is the creator of humanity and the god of fertility in the mythology of the South Pacific island of Rapa Nui, or Easter Island. He was the chief god of the Tangata manu bird-man cult and was worshiped in the form of sea birds, which were his incarnation. His material symbol was a man with a bird's head.
