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).
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 ...
NEO Surveyor, formerly called Near-Earth Object Camera (NEOCam), ... Proposals for NEOCam were submitted to NASA's Discovery Program in 2006, 2010, 2015, ...
In low-earth orbit, objects can collide at around 23,000 miles an hour, enough for even the tiniest debris to crack the windows on the International Space Station. Nearly 30,000 objects are ...
The Lincoln Near-Earth Asteroid Research (LINEAR) project is a collaboration of the United States Air Force, NASA, and the Massachusetts Institute of Technology's Lincoln Laboratory for the systematic detection and tracking of near-Earth objects.
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 ...
