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.Naming citation (MPC batch dated 2020-02-05), IAU / Minor Planet Center, via NASA/JPL
