Amor

1221 Amor is an asteroid and near-Earth object on an eccentric orbit, approximately 1 kilometer (0.6 miles) in diameter. It is the namesake of the Amor asteroids, the second-largest subgroup of near-Earth objects. It was discovered by Eugène Delporte at the Uccle Observatory in 1932, the first time that an asteroid was seen to approach Earth so closely. The assumed S-type asteroid is one of few low-numbered asteroids for which no rotation period has been determined. It was assigned the provisional designation 1932 EA1 and named for Cupid, also known as "Amor" in Latin, the Roman equivalent of the Greek god Eros.
