2015 KE172, internal designation o5m72, is a distant resonant trans-Neptunian object on an eccentric orbit in the outermost region of the Solar System, approximately 100 kilometers (60 miles) in diameter. It was first observed on 21 May 2015 by astronomers with the Outer Solar System Origins Survey at the Mauna Kea Observatories on the island of Hawaii, United States. It came to perihelion (closest approach to the Sun) in October 2017 at a distance of 44.1 AU (6.60 billion km). Its existence was first released in February 2018, and the observations and orbit were announced on 27 April 2018. It belongs to the most distant resonant objects known to exist.
