2014 YA50 is a medium-sized trans-Neptunian object orbiting the Sun as a classical Kuiper Belt object in the outer reaches of the Solar System. The object was discovered on 25 December 2014 by Pan-STARRS 1, at the Haleakala Observatory in Hawaii, United States, but the discovery was announced on 16 July 2016.[2] Michael E. Brown suggested that 2014 YA50 is large enough that it could be a dwarf planet,[8] however transneptunian bodies smaller than 900–1,000 km are unlikely to be fully solid bodies, and thus not dwarf planets.

It has been observed with precovery images back to 2002.[3]
