2357 Phereclos /ˈfɛrɪkləs/ is a large Jupiter trojan from the Trojan camp, approximately 95 kilometers (59 miles) in diameter. It was discovered on 1 January 1981, by American astronomer Edward Bowell at the Anderson Mesa Station near Flagstaff, Arizona, in the United States.[1] The dark and possibly spherical D-type asteroid belongs to the 30 largest Jupiter trojans and has a rotation period of 14.4 hours.[4] It was named after the shipbuilder Phereclos from Greek mythology.[1]
