1993 RP is a resonant trans-Neptunian object from the Kuiper belt in the outermost Solar System, approximately 70 kilometers in diameter. It was first observed on 15 September 1993, by astronomers at the Mauna Kea Observatory, one night after (385185) 1993 RO and the night before (15788) 1993 SB. Like Pluto, it is probably a plutino, which are objects that stay in a 2:3 orbital resonance with Neptune.[3]
1993 RP orbits the Sun at a distance of 34.9–43.8 AU once every 246 years and 8 months (90,089 days). Its orbit has an eccentricity of 0.11 and an inclination of 3° with respect to the ecliptic.[1] No rotational lightcurves have been obtained from photometry.[4]
