  3. Near-Earth object - Wikipedia

    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 ...

    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).

    As of September 2023, there are over 32,955 near-Earth objects of which roughly 1,620 near-Earth asteroids are listed on the risk table. [1] Only around 19 objects on the risk table are large enough to qualify as potentially hazardous objects with a diameter greater than 140 meters (absolute magnitude brighter than 22). About 99% of the objects ...

    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).

    en.wikipedia.org/wiki/Near_Earth_Object...

    The Near Earth Object Surveillance Satellite (NEOSSat) [8] is a Canadian microsatellite using a 15-cm aperture f/5.88 Maksutov telescope (similar to that on the MOST spacecraft), with 3-axis stabilisation giving a pointing stability of ~2 arcseconds in a ~100 second exposure.
