An asteroid nearly the size of a football field now has roughly a 0.28% chance of hitting Earth in about eight years, NASA says — though at one point earlier its estimate reached as high as 3.1%.

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 ...

Update: The odds of asteroid 2024 YR4 striking Earth in 2032 have fallen to 1.5%, NASA announced Wednesday. Read the latest. The risk that an increasingly ominous asteroid dubbed 2024 YR4 will ...

NASA has upgraded the risk of asteroid 2024 YR4 hitting Earth in 2032 to 3.1 per cent, or about a 1-in-32 chance, the highest odds yet of collision. Astronomers discovered that the asteroid was ...

Not much is known about 2024 YR4, but the asteroid is estimated to be 131 to 295 feet (40 to 90 meters) wide, a “size range comparable to that of a large building,” said Dr. Paul Chodas ...

Astronomers have been keeping a close eye on an asteroid between 130 and 300 feet long that has a very small chance of crashing into Earth in less than eight years. And as they learn more about ...

In December, the Asteroid Terrestrial-impact Last Alert System (ATLAS), located in Chile, identified an asteroid they automatically designated 2024 YR4. The solar system is flooded with asteroids ...
