Amor asteroid

asteroid that has an orbital semi-major axis greater than 1 AU (a > 1.0 AU) and a perihelion greater than Earth's aphelion distance (q > 1.017 AU), but is also a near-Earth object (q < 1.3 AU)

An amor asteroid is a group of asteroids found near Earth that were named after 1221 Amor. While some other kinds of asteroids cross over Mars' and Earth's orbits, nearly all of the amor asteroids do not. The best known amor asteroid is 433 Eros. It circled around and landed upon by the NEAR Shoemaker. About 1,200 of all the asteroids in space are amor asteroids, with about 200 of them numbered, or given a number. Only 50 amor asteroids are named.
