}}
, also written 2011 HM102, is the ninth Neptune trojan discovered. It was first observed on April 29, 2011 by the ''New Horizons'' KBO Search Survey. It has the same orbital period as Neptune and orbits at the Lagrangian point about 60 degrees backwards of Neptune.
==Orbit==
follows a low-eccentricity (0.08) orbit, and its semi-major axis (30.05 AU) is very similar to Neptune's (30.10 AU), orbiting in a 1:1 mean-motion resonance with it. It has a high orbital inclination of 29.42°.〔 This large value makes , as of July 2013, the highest-inclination Neptune trojan known.〔 has been observed 145 times, over two oppositions.〔
