(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]
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.
