1437 Diomedes /ˌdaɪəˈmiːdiːz/ is a large Jupiter trojan from the Greek camp, approximately 150 kilometers (90 miles) in diameter. It was discovered on 3 August 1937, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany. The dark D/P-type asteroid belongs to the largest Jupiter trojans and has a notably elongated shape and a longer than average rotation period of 24.49 hours. Diomedes was the first Jupiter trojan successfully observed during an occultation event of star. It was named after the hero Diomedes from Greek mythology.
