    (65407) 2002 RP120, provisional designation 2002 RP120, is a trans-Neptunian object with a cometary-like, eccentric orbit, also classified as a damocloid, which means it is a member of a small group of retrograde bodies. It measures approximately 15 kilometers (9.3 miles) in diameter and was probably ejected from the ecliptic by Neptune. It is a slow rotator and potentially a tumbler as well.[4]
