(120348) 2004 TY364, also written as (120348) 2004 TY364, is a trans-Neptunian object that resides in the Kuiper belt. It was discovered by Michael E. Brown, Chad Trujillo and David L. Rabinowitz on October 3, 2004 at the Palomar Observatory.
Since it has an absolute magnitude of 4.5, it is a likely dwarf planet, and Michael E. Brown's website lists it as one.[3] However, light curve analysis has questioned whether it would truly qualify as a dwarf planet.[4]
It is currently 39.5 AU from the Sun.[2]
