    en.wikipedia.org/wiki/Near-Earth_object

    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 ...

    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).

    In 2013, NASA reactivated the WISE telescope to search for near-Earth objects (NEO), such as comets and asteroids, that could collide with Earth. [12] [13] The reactivation mission was called Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). [13] As of August 2023, NEOWISE was 40% through the 20th coverage of the full sky ...

    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).

    en.wikipedia.org/wiki/Near-Earth_Asteroid_Tracking

    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 ).
