2012 HE85
2012 HE85 is a small, resonant trans-Neptunian object from the Kuiper belt, located in the outermost region of the Solar System, approximately 74 kilometers (46 miles) in diameter. It was first observed by a team of astronomers using one of the Magellan Telescopes in Chile during the New Horizons KBO Search on 18 April 2012, in order to find a potential flyby target for the New Horizons spacecraft. The likely 5:9 resonant object was imaged by the spacecraft from afar at a record distance from Earth in 2017.
