Asteroid 2024 YR4 won’t hit Earth in December 2032, but that doesn’t mean we’re out of the woods forever. Researchers warn ...

The threat from near-Earth asteroid 2024 YR4 may have subsided, but discoveries of other hazardous space rocks are set to ...

YR4, which orbits the sun every four years and periodically crosses Earth's orbit. The nature of its orbit makes it a potentially hazardous object (PHO), meaning it could pose a collision risk to ...

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

The resonant “pumping” stretching the orbit both inward and outward from the asteroid belt has already made 2024 YR4 cross Earth’s orbit, giving it a chance to impact. The much more ...

For example, Asteroid 2024 MK made an unexpectedly close approach to Earth last year, just 13 days after its discovery. The encounter altered its orbit, bringing it closer to Earth than previously ...

Additional telescope observations enabled astronomers to better calculate its orbit. In January ... that the probability of asteroid 2024 YR4 hitting Earth in 2023 was 3.1 percent, the highest ...

Donaldjohanson, a main belt asteroid, could be a relic of a cosmic collision that took place 150 million years ago.

New Southwest Research Institute-led modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about ...
