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

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

NASA is monitoring three aircraft-sized asteroids that will zoom past the Earth later today at around 19,000 to 22,200 miles per hour.

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

Asteroids—small, rocky masses left over from the formation of the solar system around 4.6 billion years ago—are found concentrated in the main asteroid belt, orbiting around the sun between the paths ...

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.

A privately-built spacecraft has embarked on an unprecedented deep space mission to scout out an asteroid's potential for mining. The probe, called Odin, was launched on a SpaceX rocket alongside ...

NASA gave the all-clear Monday on an asteroid that previously had a chance of colliding with Earth in 2032. While its odds had briefly risen to a record high of 3.1%, they have now dropped to near ...

After two months of observations, NASA scientists have officially declared Earth safe from “city-killer” asteroid 2024 YR4. On Tuesday, the space agency recently placed space rock’s impact ...

The asteroid, measuring between 130 to 300 feet wide, was discovered in December 2024. While the risk to Earth is negligible, 2024 YR4 has a slightly higher chance of impacting the moon.
