| Group | Description | Definition |
|---|---|---|
| NECs | Near-Earth Comets | q<1.3 AU, P<200 years |
| NEAs | Near-Earth Asteroids | q<1.3 AU |
| Atiras | NEAs whose orbits are contained entirely with the orbit of the Earth (named after asteroid 163693 Atira). | a<1.0 AU, Q<0.983 AU |
| Atens | Earth-crossing NEAs with semi-major axes smaller than Earth's (named after asteroid 2062 Aten). | a<1.0 AU, Q>0.983 AU |
| Apollos | Earth-crossing NEAs with semi-major axes larger than Earth's (named after asteroid 1862 Apollo). | a>1.0 AU, q<1.017 AU |
| Amors | Earth-approaching NEAs with orbits exterior to Earth's but interior to Mars' (named after asteroid 1221 Amor). | a>1.0 AU, 1.017<q<1.3 AU |
| PHAs | Potentially Hazardous Asteriods: NEAs whose Minimum Orbit Intersection Distance (MOID) with the Earth is 0.05 AU or less and whose absolute magnitude (H) is 22.0 or brighter. | MOID<=0.05 AU, H<=22.0 |
