2006 RJ₂ is a centaur and damocloid on a retrograde and highly eccentric orbit from the outer region of the Solar System. It was first observed on 14 September 2006 by the Catalina Sky Survey at the Catalina Station near Tucson, Arizona, United States. It has not been observed since 2006.[1] This unusual object measures approximately 3 kilometers (1.9 miles) in diameter.[3]
