(120348) 2004 TY364, also written as (120348) 2004 TY364, is a trans-Neptunian object. It is an inner classical Kuiper belt object in the definition by Gladman, Marsden, and Van Laerhoven (e<0.24).[1] Its inclination of almost 25 degrees disqualifies it as such in Marc Buie's definition[specify].[2] It is also not listed as a scattered disc object by the Minor Planet Center.[7] 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.[8] However, light-curve analysis has questioned whether it really is one.[9]
As of 2014[update], it is 39.2 AU from the Sun.[6]
