2002 GB32, is a trans-Neptunian object from the scattered disc in the outermost region of the Solar System, approximately 122 kilometers in diameter.[3][4] It was first observed on 7 April 2002, by American astronomer Marc Buie at Cerro Tololo Observatory in Chile.[1][2]

Description

2002 GB32 belongs to a small number of detached objects with perihelion distances of 30 AU or more, and semi-major axis of 200 AU or more.[5] Such objects can not reach such orbits without some perturbing object, which lead to the speculation of Planet Nine.

This minor planet orbits the Sun at a distance of 35.3–402.7 AU once every 3,241 years and 1 month (1,183,810 days). Its orbit has an eccentricity of 0.84 and an inclination of 14° with respect to the ecliptic.[3]

Based on an absolute magnitude of 7.8 and an assumed albedo of 0.09, the Johnston's Archive calculated a mean-diameter of 122 kilometers.[4]
