(612533) 2002 XV₉₃ (provisional designation 2002 XV₉₃) is a trans-Neptunian object (TNO) with an absolute magnitude of 5.4.^[5] 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

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.

The size of 2002 XV₉₃ has been measured by the Herschel Space Telescope to be 549.2+21.7
−23.0 km.^[5]
