(144897) 2004 UX10 is a Kuiper-belt object. It has a diameter of about 360 kilometres (220 mi) and was discovered by Andrew Becker, Andrew Puckett and Jeremy Kubica on 20 October 2004 at Apache Point Observatory in Sunspot, New Mexico. The object is a plutino (in 2:3 resonance with Neptune).
Brown estimates it is likely a dwarf planet based on its presumed size, calculated from its absolute magnitude (H) and assumed albedo.
Orbit and rotation
(144897) 2004 UX10 is a plutino in 2:3 resonance with Neptune. This fact was established by integrating its motion over 10 million years. The object is currently at 39 AU from the Sun.
The rotational period of (144897) 2004 UX10 is 5.68 h.
The size of (144897) 2004 UX10 was measured by the Herschel Space Telescope to be 361+124
−94 km. The mass of the object is currently unknown but should be greater than about 3×1019 kg.
(144897) 2004 UX10 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.
