2594 Acamas /ˈækəməs/ is a mid-sized Jupiter trojan from the Trojan camp, approximately 25 kilometers (16 miles) in diameter. It was discovered on 4 October 1978, by American astronomer Charles Kowal at the Palomar Observatory in California.[1] The dark Jovian asteroid has a longer-than average rotation period of 26 hours and possibly an elongated shape.[7] It was named after the Thracian leader Acamas from Greek mythology.[1]
