(455502) 2003 UZ413 (provisional designation 2003 UZ413) is a trans-Neptunian object (TNO) with an absolute magnitude of 4.38.[5] It is in a 2:3 orbital resonance with Neptune, thus it is classified as a plutino.[3] There are indications it may be dense enough to be a dwarf planet. It was given the minor planet number 455502 on 22 February 2016.[11]

2003 UZ413 has been observed 79 times over 15 oppositions, with precovery images back to 27 July 1954.[2]
