2002 XV93, also written as 2002 XV93, is a trans-Neptunian object (TNO) with an absolute magnitude of 5.4. A 2:3 orbital resonance with Neptune makes it a plutino.

It has been observed with precovery images back to 1990.

Orbit and rotation

2002 XV93 is locked in 2:3 resonance with Neptune, which means that when it makes two revolutions around the Sun, Neptune makes exactly three.

The rotation period of this object is not known.

Physical characteristics

The size of 2002 XV93 has been measured by the Herschel Space Telescope to be 549.2
−23.0 km.

It is likely a dwarf planet.
