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.[1] 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.[5] Diomedes was the first Jupiter trojan successfully observed during an occultation event of star.[9] It was named after the hero Diomedes from Greek mythology.[3]
