225088 Gonggong           Discovered 2007 July 17 by M. E. Schwamb, M. E. Brown and D. Rabinowitz at Palomar.
Gonggong is a Chinese water god with red hair and a serpent-like tail. He is known for creating chaos, causing flooding, and tilting the Earth; he is often depicted with the head of a human and the body of a snake. Gonggong is often attended by his minister, Xiangliu, a nine-headed poisonous snake monster for whom the satellite is named.
