An asteroid between about 130 and 300 ft. (40 and 90 meters) in diameter has been given a 2.3% chance of it hitting Earth on Dec. 22, 2032.

Scientists have finally had a close look at the rubble collected by a NASA spacecraft from an asteroid. In it, they've found new clues about the ingredients for life that were present in the early ...

He noted that many asteroids are loose rubble piles of sand ... there might not be enough time to significantly alter the asteroid’s path, warned the scientist. He noted that YR4 is arriving ...

Soon, the asteroid will be too dim even for the largest ... Does it have a lot of metallic content? Is it a rubble pile? Is it a solid, monolithic object?" NASA's Fast wonders aloud.

Asteroid 2024 YR4 isn't big enough to annihilate humanity, thankfully, but it could still reduce a city to rubble, potentially killing millions of people. Traveling at 30,000 mph, it would release ...

Asteroid 2024 YR4 poses a potential risk to the Moon, with a 1.7% chance of collision despite Earth now being safe. If it ...

However, many asteroids are known to be rubble piles, essentially collections of rocks held together loosely by gravity, such as the asteroid Bennu that was visited by NASA’s ORISIS-REx spacecraft.

Soon, the asteroid will be too dim even for the largest ... Does it have a lot of metallic content? Is it a rubble pile? Is it a solid, monolithic object?" NASA's Fast wonders aloud.

Dai said the potential death toll "mainly depends on where the asteroid impact occurs." Scientists know a great deal about Bennu, considered a "rubble pile" asteroid — a loose amalgamation of ...
