    Description

    As of 2018, it is 43.3 AU from the Sun. [7] Currently, the closest approach possible to Neptune (MOID) is 11.2  AU (1.68  billion   km ). [1] Very little is known about the object. Based on the brightness and distance, it is estimated to be between 100 and 150 km in diameter depending on the albedo.

    1994 GV9 is the second cubewano to be given an official Minor Planet Center catalog number. [2] The first cubewano is 15760 Albion.
