(144897) 2004 UX10 (provisional designation 2004 UX10) is a Kuiper-belt object. It has a diameter of about 360 kilometres (220 mi)[5] and was discovered by Andrew Becker, Andrew Puckett and Jeremy Kubica on 20 October 2004 at Apache Point Observatory in Sunspot, New Mexico.[2] The object is classified as a cubewano.[3][4] It is near a 2:3 resonance with Neptune.[5][7]

It is estimated by astronomer Michael E. Brown to likely be a dwarf planet based on its presumed size, calculated from its absolute magnitude (H) and assumed albedo.[10]
