2015 KH₁₆₃, is a trans-Neptunian object discovered at Mauna Kea on May 24, 2015.

It is one a small number of detached objects with perihelion distances of 30 AUs or more, and semi-major axes of 200 AU or more.^[1] Such objects can not reach such orbits without some perturbing object, which lead to the speculation of planet nine.
