, previously known as, is an extreme trans-Neptunian object orbiting in the Kuiper belt of the outermost Solar System. It was first observed by the Outer Solar System Origins Survey using the Canada–France–Hawaii Telescope at Mauna Kea on 25 February 2015.

Description
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. Such objects cannot reach such orbits without some perturbing object, which has led to the Planet Nine hypothesis, that a massive trans-Neptunian planet is the perturber.
