65489 Ceto           Discovered 2003 Mar. 22 by C. A. Trujillo and M. Brown at Palomar.
The satellite (65489) Ceto I, discovered 2006 Apr. 11 by K. Noll, H. Levison, W. Grundy and D. Stephens using the Hubble Space Telescope, is named Phorcys, for another child of Gaia and Pontus. Phorcys is represented with a man's head, crab's claws and a fish tail. Together the monstrous sea creatures Ceto and Phorcys produced numerous offspring, including many monstrous creatures known collectively as the Phorcydides.
