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. It is a lost minor planet that has only been observed six times on the nights of 3–4 April 1995, by David Jewitt and Jun Chen at the Mauna Kea Observatory, Hawaii, using the UH88 telescope, and has not been observed ever since. The object is estimated to have been discovered right at perihelion (closest approach to the Sun) at a distance of 39±1900 AU from the Sun. 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
