Articles about near-Earth objects, including any small Solar System body whose orbit brings it into 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).
Near-Earth comets (NECs) are objects in a near-Earth orbit with a tail or coma made up of dust, gas or ionized particles emitted by a solid nucleus. Comet nuclei are typically less dense than asteroids but they pass Earth at higher relative speeds, thus the impact energy of a comet nucleus is slightly larger than that of a similar-sized ...
NEODyS [1] (Near Earth Objects Dynamic Site) is an Italian service that provides information on near-Earth objects with a Web-based interface. It is based on a continually and (almost) automatically maintained database of near earth asteroid orbits. This site provides a number of services to the NEO community.

A larger object of 2–3 Jupiter masses would be visible at a distance of up to 7–10 light years. [22] At the time of planning, it was estimated that WISE would detect about 300,000 main-belt asteroids, of which approximately 100,000 will be new, and some 700 Near-Earth objects (NEO) including about 300 undiscovered. That translates to about ...
The Center for Near-Earth Object Studies (CNEOS) is the Jet Propulsion Laboratory's (JPL's) facility for computing asteroid and comet orbits and their probability of Earth impact. [1] [2] CNEOS is located at, and operated by, Caltech in Pasadena, California. CNEOS computes high-precision orbits for Near-Earth Objects (NEOs).
DANEOPS, the DLR-Archenhold Near Earth Objects Precovery Survey, has been initiated to systematically search existing photographic plate archives for precovery images of known NEOs, and has thus far successfully precovered 146 objects.
