1995 GJ with an inclination of 22.9° may be the first cubewano (classical KBO) discovered to have an inclination greater than 20 degrees. Most cubewanos have inclinations of less than 10 degrees.

Given the long orbit that KBOs take around the sun, 1995 GJ comes to opposition in mid March of each year at an apparent magnitude of 22.9. Unfortunately, this object was only observed six times over the two nights of 1995 April 3rd-4th and its orbit is very inaccurate.cite web

accessdate=2008-05-22] It even has an assumed eccentricity.

1995 GJ was discovered by David C. Jewitt and J. Chen at the Mauna Kea Observatory, Hawaii using the 88-inch (2.2-meter) University of Hawaii telescope.
