1995 GJ might be a trans-Neptunian object and/or high-inclination cubewano from the Kuiper belt in the outermost region of the Solar System, and based on the calculated distance and brightness is assumed to be approximately 175 kilometers (110 miles) in diameter.
[2] On the night of discovery, the object is estimated to have been moving away from Earth at 16 km/s with the uncertainty in the velocity being an unrealistic ±238000 km/s (80% the speed of light).
1995 GJ could be a trans-Neptunian object, a centaur, or a much closer main belt asteroid 100 times smaller in diameter.
As an example, (392741) 2012 SQ31 (when it had a one-day observation arc) was thought to be a potential trans-Neptunian dwarf planet, but is now known to be a small main belt asteroid.
Using the nominal orbit with the assumed eccentricity,[3] 1995 GJ may come to opposition around mid March of each year at an apparent magnitude of 22.9.
