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).

Smaller objects shoot past Earth all the time, according to asteroid expert Davide Farnocchia with NASA’s Center for Near-Earth Object Studies. Asteroids the size of this latest one fly by about ...
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 ...
Nasa has issued an alert for a stadium-sized asteroid set to make a close approach to Earth on Tuesday.. The 2024 ON asteroid measures 290 metres (950 feet) across and will come within 1 million ...
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).
“In fact, this is one of the closest approaches by a known near-Earth object ever recorded.” Discovered Saturday, the asteroid known as 2023 BU is believed to be between 11 feet (3.5 meters ...
