(65407) 2002 RP120 (also written (65407) 2002 RP120) is a damocloid, which means it is also a member of a small group of retrograde minor planets. Aside from being a damocloid, it is also a scattered-disc object – a trans-Neptunian object with a very eccentric orbit, probably ejected from the ecliptic by Neptune.
