(65407) 2002 RP120 holds the dubious distinction of being the most eccentric of the numbered asteroids (as of July 2004). Its classification is uncertain, as it is at once a Damocloid (a highly eccentric, highly inclined object likely to be an extinct comet) and a scattered disk object (a Trans-Neptunian object with a very eccentric orbit, likely ejected from the ecliptic by Neptune).
