1208 Troilus /ˈtroʊɪləs/ is a large and notably inclined Jupiter trojan from the Trojan camp, approximately 103 kilometers (64 miles) in diameter. It was discovered on 31 December 1931, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southern Germany.[1] The unusual F-type asteroid belongs to the largest Jupiter trojans and has a long rotation period of 56.2 hours.[6] It was named after the Trojan prince Troilus, who was killed by Achilles.[4]
