(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
[edit]
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.[2]
The rotation period of this object is currently unknown.
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.[5]
