2002 XV93, also written as 2002 XV93, is a trans-Neptunian object (TNO) with an absolute magnitude of 4.7.[6] A 2:3 orbital resonance with Neptune makes it a plutino.[2]
It has been observed with precovery images back to 1990.[3]
Contents |
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 is not known but a reasonable estimate is around 560 km.[4][5]
