(120348) 2004 TY364, also written as (120348) 2004 TY364, is a trans-Neptunian object. It may be a classical Kuiper belt object with a high inclination of 24 degrees. It was discovered by Michael E. Brown, Chad Trujillo and David L. Rabinowitz on October 3, 2004 at the Palomar Observatory.
With an absolute magnitude of 4.5, it is likely a dwarf planet.[4] However, light curve analysis has questioned whether it really is a one.[6]
As of 2014[update], it is 39.2 AU from the Sun.[5]
