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

Orbiting between Mars and Jupiter is an enormous ring of space rocks. The region, known as the asteroid belt, is home to an estimated 1.9 million asteroids that are larger than 1 kilometer in diameter ...

This illustration shows the creation of an asteroid family. Ejected fragments from catastrophic collisions of asteroids between Mars and Jupiter tend to follow similar orbits around the sun, allowing ...

"This has been a decade-long detective story, with each recorded meteorite fall providing a new clue." Ten years ago, astronomers from various institutions, including NASA and SETI (Search for ...

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 ...

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 ...

Asteroid ‘Families’ Reveal Hidden Histories and Impact Risks across the Solar System ...

A brand-new group of frozen objects, orbiting the sun out beyond the distant Kuiper Belt, has been spotted by the Subaru telescope, working with NASA's New Horizons mission to find new targets for the ...

If such ‘twilight’ asteroids approach Earth, "they could pose serious impact hazards," warned the astronomer behind the ...

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 ...

Asteroids that orbit close to the Earth inevitably cause us some anxiety due to the even remote possibility of a collision. But their proximity also offers ample opportunities to learn more about the ...
