1221 Amor /ˈæmɔːr/ 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.[1] The assumed S-type asteroid is one of few low-numbered asteroids for which no rotation period has been determined.[8] 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.[4]
