2202 Pele, provisional designation 1972 RA, is an eccentric asteroid and near-Earth object of the Amor group, approximately 1–2 kilometers in diameter.
It was discovered by American astronomer Arnold Klemola at the U.S. Lick Observatory on Mount Hamilton, California, on 7 September 1972.[3] The asteroid was named after Pele from native Hawaiian religion.[2]
Pele orbits the Sun at a distance of 1.1–3.5 AU once every 3 years and 6 months (1,265 days). Its orbit has an eccentricity of 0.51 and an inclination of 9° with respect to the ecliptic.[1]
It is an Amor asteroid, the second largest subgroup of near-Earth objects, that approach the orbit of Earth from beyond, but does not cross it. It has an Earth minimum orbit intersection distance of 0.1426 AU (21,330,000 km), which corresponds to 55.6 lunar distances.
No precoveries were taken. The asteroid's observation arc starts two days after the official discovery observation.[3]
