2004 KV18 is an eccentric Neptune trojan trailing Neptune's orbit in the outer Solar System, approximately 70 kilometers in diameter. It was first observed on 24 May 2004, by astronomers at the Mauna Kea Observatories on Hawaii, United States.[2] It was the eighth Neptune trojan identified and the second in Neptune's L5 Lagrangian point.[3]
