Neptune trojans are bodies that orbit the Sun near one of the stable Lagrangian points of Neptune, similar to the trojans of other planets. They therefore have approximately the same orbital period as Neptune and follow roughly the same orbital path. Thirty-one Neptune trojans are currently known, of which 27 orbit near the Sun–Neptune L4 Lagrangian point 60° ahead of Neptune and four orbit near Neptune's L5 region 60° behind Neptune. The Neptune trojans are termed 'trojans' by analogy with the Jupiter trojans.
385695 Clete, provisional designation 2005 TO74, is a Neptune trojan, co-orbital with the ice giant Neptune, approximately 97 kilometers (60 miles) in diameter. It was named after Clete, one of the Amazons from Greek mythology. The minor planet was discovered on 8 October 2005, by American astronomers Scott Sheppard and Chad Trujillo at Las Campanas Observatory in Chile. 23 known Neptune trojans have already been discovered.
