The amount of light reflected by the asteroid’s surface is used to estimate how big it is. However, the Webb telescope, slated to begin observations of 2024 YR4 in early March, sees the universe in ...

NASA has said Earth will likely be spared by a deadly Big Ben-sized asteroid and predicts it could smash into the Moon instead in a dramatic collision. The space agency feared the chance of a ...

YR4 has a roughly 2 percent chance of hitting Earth in 2032, and “is large enough to cause localized damage,” NASA says.

Analysis of samples brought back to Earth from the asteroid Bennu reveal that it has a bizarre chemical make-up and is ...

YR4 has a 2.3% chance of hitting Earth in the year 2032. But according to new estimates, it may have an even smaller chance of hitting the moon instead.

The asteroid is estimated to be about 40-90 meters wide, big enough to cause local devastation but not mass extinction. While the asteroid is dangerous enough to merit attention from scientists ...

Researchers say they have found "unequivocal evidence" that a meteorite smashed into Earth 3.47 billion years ago, ...

The Webb telescope is well-suited to identify asteroid 2024 YR4's size. Webb views a type of light we can't see with the naked eye, called infrared. Infrared light is largely heat energy, allowing ...

The Hera probe has swung around Mars, using the planet’s gravitational pull to fling itself toward its asteroid target. During its brief rendezvous with the Red Planet, Hera caught a glimpse of the ...

NASA announced Monday that the asteroid, named 2024 YR 4, no longer poses a “significant threat” to Earth in 2032 or beyond. “NASA analysis drops asteroid 2024 YR4's impact probability to 0.004%, ...

2024 YR4 isn't the largest asteroid out there, but it certainly isn't small, ranging from around 130 to 328 ft in diameter. It is also moving to the solar system at around 38,000 MPH. If it did ...
