It has a diameter of about {{convert|360|km|mi}}[3] 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 a plutino (in 2:3 resonance with Neptune).[3][8] It is likely a dwarf planet based on its absolute magnitude (H) and assumed albedo.[20] Orbit and rotation{{mp|(144897) 2004 UX|10}} is a plutino in 2:3 resonance with Neptune. This fact was established by integrating its motion over 10 million years.[3] The object is currently at 39 AU from the Sun.[12]The rotational period of {{mp|(144897) 2004 UX|10}} is 5.68 h.[2] Physical propertiesThe size of {{mp|(144897) 2004 UX|10}} was measured by the Herschel Space Telescope to be {{val|361|124|-94|u=km}}.[3] The mass of the object is currently unknown but should be greater than about 3{{e|19}} kg.[8] {{mp|(144897) 2004 UX|10}} has a moderately red slope in the visible spectral range. Its visible spectrum does not show any features, although there is a small departure from the linearity near 0.8 μm.[26]See also
