    1437 Diomedes is a Jupiter trojan orbiting near the L4 Lagrangian point of the Sun–Jupiter system, i.e. "Greek Camp". Based on IRAS data, Diomedes is 164 km in diameter, the third-largest Jupiter trojan.[4] It was discovered by Karl Wilhelm Reinmuth on 3 August 1937, in Heidelberg, Germany[1] and named after the Greek hero Diomedes
