3391 Sinon /ˈsaɪnɒn/ is a mid-sized Jupiter trojan from the Greek camp, approximately 40 kilometers (25 miles) in diameter. It was discovered on 18 February 1977, by Japanese astronomers Hiroki Kosai and Kiichirō Furukawa at the Kiso Observatory in Japan.[1] The dark Jovian asteroid has a rotation period of 8.1 hours and likely an elongated shape.[7] It was named after the hero Sinon from Greek mythology.[1]
