near-Earth object

(object orbiting the Sun that passes close to Earth)

A near-Earth object (NEO) is an object, such as a comet or asteroid, in solar orbit that passes near Earth. They are of special interest because of the potential for a future impact with Earth (those most likely are termed potentially hazardous objects or PHOs), and a number of surveys aim to identify them:

Near-Earth objects are also useful destinations for space probes, such as OSIRIS-REx visiting 101955 Bennu. Comets and asteroids passing close to Earth are among the easiest to reach.
