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

Interestingly, asteroid (20) Massalia, the parent of this family, is also an H chondrite type. Meteorites with less iron—called L and LL chondrites—mostly come from the inner asteroid belt.

Credit: NASA/JPL-Caltech A team of astronomers has spent over a decade tracing meteorite impacts on Earth back to their original sources in the asteroid belt. By building a global network of sky ...

A recent study models an alternate version of our solar system, one where an extra planet, rather than an asteroid belt, formed between Mars and Jupiter. Credit: SciTechDaily.com Could a giant planet ...

In a review paper in the journal Meteoritics & Planetary Science, published online this week, astronomers trace the impact orbit of observed meteorite falls to several previously unidentified source ...

The Kirkwood gaps are explained by asteroids similarly interacting with Jupiter to leave the asteroid belt, even while their average distance from the sun does not change. By dipping into the inner ...

Millions of asteroids meander throughout our solar system, a majority of which congregate in the asteroid belt between Mars and Jupiter. Rarely does a large asteroid ever hit our Earth.

Mar. 17, 2025 — New modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about 150 million years ago when a larger parent asteroid broke apart; its orbit and spin ...

Most asteroids rather conveniently live in a place between Mars and Jupiter known as the asteroid belt, but some can make their way a little closer to earth, where they can cause problems.

“Space is incredibly, profoundly empty,” Fuls said. “We don’t even check when we send probes through the asteroid belt.” Movies depict the belt as crowded and rock-filled, when in fact ...

In late 2024, astronomers spotted asteroid 2024 YR4 on a trajectory that could potentially threaten Earth. This observation triggered a fervid series of observations of the object—possibly as ...
