2002 XV93, also written as 2002 XV93, is a trans-Neptunian object (TNO) with an absolute magnitude of 5.4.[4] A 2:3 orbital resonance with Neptune makes it a plutino.[2]

It has been observed with precovery images back to 1990.[3]

Orbit and rotation[edit]

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.[2]

The rotation period of this object is not known.

Physical characteristics[edit]

The size of 2002 XV93 has been measured by the Herschel Space Telescope to be 549.2+21.7
−23.0
 km.[4]
