A vast ring of rocky leftovers between Mars and Jupiter, the asteroid belt preserves clues to how the planets — and Earth ...

Between the orbits of Mars and Jupiter lies a ring-shaped region called the asteroid belt, home to the vast majority of our solar system’s space rocks. The asteroid belt is as old as the solar system ...

A new "main-belt comet" — a comet-like object masquerading as an asteroid in the asteroid belt between Mars and Jupiter — has been identified, bringing the tally of these beguiling objects up to 14.

A NASA spacecraft recently got an up-close look at a strange peanut-shaped space rock floating through the cosmos in the main asteroid belt. Not to worry: Astronomers aren't interested in the small ...

Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the ...

Astronomers used the NASA/ESA/CSA James Webb Space Telescope to image the warm dust around a nearby young star, Fomalhaut, in order to study the first asteroid belt ever seen outside of our Solar ...

Lying between Mars and Jupiter is a massive ring of rock debris—the asteroid belt. Now thin, it’s fading away gradually. In a new study, planetary scientist Julio A. Fernández of Uruguay’s Universidad ...

Utilizing archival James Webb Space Telescope (JWST) data and novel synthetic tracking algorithms, researchers identified 138 asteroids smaller than 100 meters in diameter within the main asteroid ...

Where do meteorites of different type come from? In a review paper, astronomers trace the impact orbit of observed meteorite falls to several previously unidentified source regions in the asteroid ...

NASA is also tracking a building-sized asteroid named “2025 YC3”, with a diameter of around 260 feet, and another bus-sized ...

Asteroid 2025 XF1 is hurting through the solar system at nearly 8,000 miles per hour, according to the spacy agency.
