A Near-Earth Object or NEO, is an object within the Solar System whose orbit brings it into close proximity with the Earth. All NEOs have their closest approach to the Sun (perihelion) at less than 1.3 AU.[1] They include a few thousand Near-Earth Asteroids (NEAs), Near-Earth Comets, numerous solar-orbiting spacecraft and meteoroids large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of Earth.
