(65407) 2002 RP 120 is an asteroid with one of the largest known orbital eccentricities. It is slightly surpassed by the Trans-Neptunian Object (87269) 2000 OO 67 . 2002 RP 120 is also one of the few asteroids with a retrograde orbit.
2002 RP 120 was discovered on September 4th, 2002 by Brian A. Skiff as part of the LONEOS program. Although no signs of activity could be detected even during the perihelion passage on October 6, 2002, the “typical comet trajectory ” indicates that the object is probably an old, “burned out” comet.
