  2. NEO Surveyor - Wikipedia

    en.wikipedia.org/wiki/NEO_Surveyor

    NEO Surveyor will also be able to conduct targeted follow-up (TFO) to obtain more information for an object of special interest. [2] It is planned that moving object tracklets are delivered to the Minor Planet Center 2 to 3 times a day, on average 72 hours after their discovery. Additionally deep co-added images are published every 12 months. [2]

    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 2005, the U.S. Congress passed the NASA Authorization Act, which, in part, tasked NASA with finding and cataloguing at least 90% of all near-Earth objects that are 140 meters or larger by 2020. [ 6 ] [ 7 ] However, that goal was clearly not being met by NASA's Near Earth Object Observations Program, which a 2014 report by the NASA Office of ...

    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 ...
