Orbit and rotation

Precovery image of 2003 XV₉₃ taken by the Palomar Observatory in 1992^[8]

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

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