2011 HM102 is the ninth Neptune trojan discovered. It was first observed on 29 April 2011, during the New Horizons KBO Search (268) using the Magellan II (Clay) Telescope at Las Campanas Observatory in Chile.[2][5] It has the same orbital period as Neptune and orbits at the L5 Lagrangian point about 60° backwards of Neptune.[3]
