2015 KG163, also known as $o5m52$ , is a trans-Neptunian object discovered on May 24, 2015 by the Outer Solar System Origins Survey using the Canada–France–Hawaii Telescope on Mauna Kea.

It is one a small number of detached objects with perihelion distances of 30 AU or more, and semi-major axes of 250 AU or more.^[1] Such objects can not reach such orbits without some perturbing object, which lead to the speculation of Planet Nine. Its argument of perihelion is similar to that of 2013 FT28.
