(612533) 2002 XV93 (provisional designation 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, meaning that for every two revolutions it makes around the Sun, Neptune makes exactly three.
The rotation period of this object is currently unknown.
Physical characteristics
The size of 2002 XV93 has been measured by the Herschel Space Telescope to be 549.2+21.7
−23.0 km.
