(144897) 2004 UX10 is a Kuiper-belt object. It has a diameter of about 398 km. It was discovered on 20 October 2004. The object is a plutino (in 2:3 resonance with Neptune).
Mike Brown's website lists it as a likely dwarf planet based on its absolute magnitude (H) and assumed albedo.
Orbit and rotation
2004 UX10 was classified in the past as a Classical Kuiper Belt object. Later it was reclassified as a plutino.
It is currently at 39 AU from the Sun.
Physical properties
The size of 2004 UX120 was measured by the Herschel Space Telescope to be 398.1
−39.3.
