(612533) 2002 XV93
Trans-Neptunian object (TNO)
From Wikipedia, the free encyclopedia
(612533) 2002 XV93 (provisional designation 2002 XV93) is a medium-sized trans-Neptunian object (TNO) in the Kuiper Belt with an absolute magnitude of 5.4.[5] A 2:3 orbital resonance with Neptune makes it a plutino.[2] Michael Brown concludes that it is "likely" a dwarf planet, based on an estimated diameter of 564 km;[8] however, transneptunian bodies smaller than 900–1,000 km are unlikely to be fully solid bodies, and thus not dwarf planets.

Orbit and rotation
Numbering and naming
This minor planet was numbered by the Minor Planet Center on 28 March 2022, receiving the number 612533 in the minor planet catalog M.P.C. 138389.[9] As of January 2026[update], it has not been named.[10]
Physical characteristics
The size of 2002 XV93 has been measured by the Herschel Space Telescope to be 549.2+21.7
−23.0 km.[5] 2002 XV93 has no known moons, so its mass and density is unknown.
