    (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. [3] [ specify ] 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, it is 39.2 AU from the Sun. [7]
