This view of sample site Nightingale on asteroid Bennu is a mosaic of images collected by NASA's OSIRIS-REx spacecraft on March 3.

In February and July of 2019, the Hayabusa2 spacecraft briefly touched down on the surface of near-Earth asteroid Ryugu.

A large near-Earth asteroid will safely pass by our planet on Wednesday morning, providing astronomers with an exceptional opportunity to study the 1.5-mile-wide (2-kilometer-wide) object in great detail.

The Arecibo Observatory in Puerto Rico is following an asteroid approaching Earth this week and while it poses no threat, it appears to know our planet is facing a pandemic.

This series of images, captured on Apr. 14 during the first rehearsal of the OSIRIS-REx mission's sample collection event, shows the SamCam instrument's field of view as the spacecraft approaches and moves away from asteroid Bennu's surface.

An Iron-clad Asteroid

Itokawa would normally be a fairly average near-Earth asteroid - a rocky mass measuring only a few hundred metres in diameter, which orbits the sun amid countless other celestial bodies and repeatedly crosses the orbit of the Earth.

After a year scoping out asteroid Bennu's boulder-scattered surface, the team leading NASA's first asteroid sample return mission has officially selected a sample collection site.

A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system.

After months grappling with the rugged reality of asteroid Bennu's surface, the team leading NASA's first asteroid sample return mission has selected four potential sites for the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to "tag" its cosmic dance partner.

Earth vs. Asteroids: Humans Strike Back

Incoming asteroids have been scarring our home planet for billions of years.

NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission released its fifth year of survey data on April 11, 2019.

Metallic asteroids are thought to have started out as blobs of molten iron floating in space.

ESA's planet-defending Hera mission will set a new record in space.

Asteroid Ryugu, an ancient space rock roughly 300 million km from Earth, is now home to three Earth-born inhabitants bouncing across its bouldery surface.

An object is revolving around the sun in the vicinity of Jupiter but in the opposite direction from most other celestial bodies, according to a study featuring a Brazilian scientist as co-author.

An international team of astronomers led by NASA scientists successfully completed the first global exercise using a real asteroid to test global response capabilities.

NASA's Hubble Space Telescope helped an international team of astronomers find that an unusual object in the asteroid belt is, in fact, two asteroids orbiting each other that have comet-like features.

se flyby of a small asteroid and plan to use its upcoming October close approach to Earth as an opportunity not only for science, but to test NASA's network of observatories and scientists who work with planetary defense.

Pitted terrains inside fresh complex craters on Ceres are similar to terrains seen Mars and Vesta, and are likely formed through the rapid evaporation of subsurface H2O

Asteroids on the main belt, situated between Mars and Jupiter, move around the Sun in quasi circular orbits, so they do not undergo the temperature changes which, in comets, produce the characteristic tails.
