4792 Lykaon /lɪˈkeɪɒn/ is a dark Jupiter trojan from the Trojan camp, approximately 51 kilometers (32 miles) in diameter. It was discovered on 10 September 1988, by American astronomer Carolyn Shoemaker at the Palomar Observatory in California.[1] The possibly elongated Jovian asteroid belongs to the 100 largest Jupiter trojans and has a long rotation period of 40.1 hours.[8] It was named after the Trojan prince Lycaon from Greek mythology.[1]
