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 ...

In the distant past, the solar system was rife with impacts and collisions. Millions of rocky objects zoomed chaotically ...

A new analysis estimates that the asteroid belt is steadily losing mass each year, and may not be as permanent a feature of ...

Solar systems with life-bearing planets may be rare if they are dependent on the presence of asteroid belts of just the right mass, according to a study by Rebecca Martin, a NASA Sagan Fellow from 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 ...

Let’s be honest: the asteroid belt is a bit of a mess. It is full of big rocks hurtling around at high speeds, occasionally getting tossed towards assorted planets, and generally causing a ruckus. On ...

Astronomers have discovered asteroid 2025 SC79, a skyscraper-sized space rock orbiting the sun in just 128 days. the ...

As mankind was planning the first moon landing in the 1960s, an asteroid approached Earth—and still hasn’t left.

In an article published in the journal Icarus, researchers at São Paulo State University (UNESP) and collaborators report the findings of a study reconstituting the formation of the dwarf planet Ceres ...

THAT’s NO MOON - Earth doesn’t just have one moon; sometimes, it has a companion satellite or “mini-moon.” Discovered on ...

Millions of asteroids, not a planet, exist in the asteroid belt. The asteroid belt's total mass is only a small fraction of the Moon's mass. Meteorite analysis suggests the asteroids didn't originate ...
