(144897) 2004 UX10 is a Kuiper-belt object. It has a diameter of about 360 kilometres (220 mi)[2] and was discovered by Andrew Becker, Andrew Puckett and Jeremy Kubica on 20 October 2004 at Apache Point Observatory in Sunspot, New Mexico.[3] The object is a plutino (in 2:3 resonance with Neptune).[2][4]
It is likely a dwarf planet based on its absolute magnitude (H) and assumed albedo.[6]
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.[2] The object is currently at 39 AU from the Sun.[5]
The rotational period of (144897) 2004 UX10 is not known but is likely to lie in the range of 5 to 7 hours.[4]
Physical properties
The size of (144897) 2004 UX10 was measured by the Herschel Space Telescope to be 361+124
−94 km.[2] The mass of the object is currently unknown but should be greater than about 3×1019 kg.[4]
(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.[7]
