(95625) 2002 GX32, also written as (95625) 2002 GX32, is a trans-Neptunian object that resides in the Kuiper belt.[2] It has a 3:7 resonance with Neptune.[3] It was discovered on April 8, 2002 by Marc W. Buie, Amy B. Jordan, and James L. Elliot.

It came to perihelion in 1997.[1]

Assuming a generic TNO albedo of 0.09, it is about 153 km in diameter.[6]

Resonance

Simulations by Emel’yanenko and Kiseleva in 2007 show that (95625) 2002 GX32 has a 99% probability of librating in a 3:7 resonance with Neptune.[7]

The Neptune 3:7 mean-motion resonance keeps it more than 11 AU from Neptune over a 14000-year period.[4]

It has been observed 21 times over 4 oppositions and has an orbit quality code of 3.[1]

The orbital period of both 2002 GX32 and 2001 XT254 around the 3:7 (2.333) resonance of Neptune.
