(120348) 2004 TY364, also written as (120348) 2004 TY364, is a trans-Neptunian object. With an inclination of 24 degrees, it does not qualify as a classical Kuiper belt object,[1] but is also not listed as a scattered disc object by the Minor Planet Center.[6] 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.[7]
As of 2014[update], it is 39.2 AU from the Sun.[5]
