(120348) 2004 TY364, provisionally known as 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).[2] Its inclination of almost 25 degrees disqualifies it as such in Marc Buie's definition[specify].[3] It is also not listed as a scattered disc object by the Minor Planet Center.[8] It was discovered by Michael E. Brown, Chad Trujillo and David L. Rabinowitz on October 3, 2004 at the Palomar Observatory.
Light-curve analysis suggests it is not a dwarf planet.[9]
As of 2014[update], it is 39.2 AU from the Sun.[7]
