A near-Earth object ( NEO) is any small Solar System body orbiting the Sun whose closest approach to the Sun ( perihelion) is less than 1.3 times the Earth–Sun distance ( astronomical unit, AU). [2] This definition applies to the object's orbit around the Sun, rather than its current position, thus an object with such an orbit is considered ...

The other object that flashes by is an artificial satellite. A near-Earth object ( NEO) is a Solar System object whose orbit brings it close to the Earth. Their least distance from the Sun, their perihelion, is less than 1.3 AU. [1] [2] NEOs include near-Earth asteroids (NEAs) and near-Earth comets. [2]

May 1, 2023 · The Near-Earth Object Program coordinates NASA-sponsored efforts to detect, track and characterize potentially hazardous asteroids and comets that could approach the Earth. Stay up-to-date on which asteroids and comets wander near Earth. The website shows distances that the closest asteroids and comets are to our home planet.
Jul 23, 2018 · Twenty Years of Tracking Near-Earth Objects. July 23, 2018. The animation depicts a mapping of the positions of known near-Earth objects (NEOs) at points in time over the past 20 years, and finishes with a map of all known asteroids as of January 2018. Asteroid search teams supported by NASA's NEO Observations Program have found over 95 percent ...
A larger object of 2–3 Jupiter masses would be visible at a distance of up to 7–10 light years. At the time of planning, it was estimated that WISE would detect about 300,000 main-belt asteroids, of which approximately 100,000 will be new, and some 700 Near-Earth objects (NEO) including about 300 undiscovered. That translates to about 1000 ...
Apr 26, 2024 · A History of Near-Earth Objects Research. By Erik M. Conway, Donald K. Yeomans, and Meg Rosenburg. In 2016, NASA took on a new responsibility: defending our planet from devastating impacts by asteroids and comets that approach the Earth, or near-Earth objects. That event, which followed the prominent Chelyabinsk meteor explosion in 2013 ...
The NEAR Shoemaker probe visited Eros twice, first with a brief flyby in 1998, and then by orbiting it in 2000, when it extensively photographed its surface. On 12 February 2001, at the end of its mission, it landed on the asteroid's surface using its maneuvering jets. This was the first time a Near Earth asteroid was closely visited by a ...
