The asteroid 2024 YR4, once considered potentially hazardous, isn't likely to hit us anytime soon. Now, a team of researchers ...

Where do meteorites of different types come from? In a review paper in the journal Meteoritics & Planetary Science, ...

"Scientifically there's a huge amount we can learn from asteroids," says Alan Fitzsimmons, an astronomer at Queens University ...

For centuries, scientists have sought to understand the origins of meteorites that fall to Earth. Recent research has ...

"This has been a decade-long detective story, with each recorded meteorite fall providing a new clue," said one astronomer.

In December 2024, astronomers in Chile spotted a new asteroid streaking through the sky, which they named 2024 YR4. What’s significant about this 100m-wide space rock is that it has a small chance of ...

YR4, which orbits the sun every four years and periodically crosses Earth's orbit. The nature of its orbit makes it a ...

The latest calculations indicate that the asteroid known as 2024 YR4 is much less likely to hit Earth than earlier measurements had suggested. Late on 19 February, telescopic observations of the ...

New simulations reveal that the climate, atmospheric chemistry and even global photosynthesis would be dramatically disrupted by an asteroid collision ...

Jenniskens and Devillepoix find that low iron (L chondrite) and very low iron (LL chondrite) meteorites come to us primarily from the inner main belt. Scientists have long linked the LL chondrites to ...

The narrow difference is due to the two agencies’ use of different tools for determining the asteroid’s orbit and modeling its potential impact. But both percentages rise above the 2.7% chance ...
