Near-Earth Asteroid Tracking (NEAT) was a program run by NASA and the Jet Propulsion Laboratory, surveying the sky for near-Earth objects.NEAT was conducted from December 1995 until April 2007, at GEODSS on Hawaii (Haleakala-NEAT; 566), as well as at Palomar Observatory in California (Palomar-NEAT; 644).With the discovery of more than 40 thousand minor planets, NEAT has been one of the most ...

The Asteroid Watch Widget tracks asteroids and comets that will make relatively close approaches to Earth. The Widget displays the date of closest approach, approximate object diameter, relative size and distance from Earth for each encounter. The object's name is displayed by hovering over its encounter date.

A near-Earth object (NEO) is any small Solar System body whose orbit brings it to proximity with Earth.By convention, a Solar System body is a NEO if its closest approach to the Sun is less than 1.3 astronomical units (AU).If a NEO's orbit crosses the Earth's, and the object is larger than 140 meters (460 ft) across, it is considered a potentially hazardous object (PHO).

Since NASA’s initiation of the NEO Observations program in 1998, Near-Earth Object (NEO) surveys have been extremely successful finding more than 90% of the Near-Earth Asteroids (NEAs) larger than one kilometer and a good fraction of the NEOs larger than 140 meters.
