5638 Deikoon /diːˈɪkoʊɒn/ is a mid-sized Jupiter trojan from the Trojan camp, approximately 44 kilometers (27 miles) in diameter. It was discovered on 10 October 1988 by American astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory in California.[1] The dark and possibly spherical D-type asteroid has a rotation period of 19.4 hours.[7] It was named after the Trojan hero Deicoon from Greek mythology.[1]
