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).
The space rock last made a pass of Earth in 2013, and will make another approach in 2035, according to Nasa’s data. The object was first spotted by Nasa’s Near-Earth Object (NEO) Observations ...

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 ).
