New Southwest Research Institute-led 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 ...

Although NASA's Lucy spacecraft's upcoming encounter with the asteroid Donaldjohanson is primarily a mission rehearsal for ...

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

NASA’s OSIRIS-REx mission returned samples from asteroid Bennu, which showed discoveries about life and the early solar system. These findings can now provide information into the potential origins of ...

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

The precise VLT observations, along with data collected by other observatories, allowed astronomers to more accurately model the asteroid's orbit and assess its impact probability, according to a ...

Countless asteroids in our solar system, some close, some far — but did you know that some of these space rocks have names?

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

Up until August 2024, the WISE spacecraft was one such observatory. The telescope was repurposed for asteroid and comet tracking after its original mission ended. In the next few years ...

NASA is on high alert for a “city-killer” asteroid that’s headed toward Earth — cuz they don’t wanna miss a thing. The asteroid, called 2024 YR4, now has a 1.5% probability of hitting ...

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 ...

An asteroid nearly the size of a football field now has roughly a 0.004% chance of hitting Earth in about eight years, NASA says — with the space agency saying it "no longer poses a significant ...
