YR4 has just above a 1% chance of crashing into Earth in 2032, which is why astronomers and space agencies are paying attention to it.

In the case of Apophis, further observations eventually allowed astronomers in 2021 to rule out the possibility of an impact when the asteroid makes a close flyby to Earth in 2029 and again in 2036.

Researchers are unlocking secrets of our solar system by analyzing asteroid Bennu samples, some of the most pristine ever collected. These fragments date back 4.5 billion years and contain salts, ...

Asteroid 2024 YR4 has been a source of consternation because it carries an uncommonly high risk of colliding into Earth. It's the most hazardous space rock detected since astronomers first ...

The chance of a newly discovered space rock hitting Earth in about eight years was predicted at 1.6 percent last week. Though ...

The object, classified as a near-Earth asteroid because its orbit would bring it within 30 million miles of Earth, is the most hazardous space rock detected since astronomers first discovered the ...

This happened with the asteroid Apophis — a 1,100-foot-wide behemoth that once had a small chance of impacts in both 2029 and 2036. But more precise telescope observations moved Apophis' range ...

For example, the asteroid Apophis was once considered one of the most hazardous asteroids, with the potential to strike Earth after its discovery in 2004. In 2021, scientists revised that opinion ...
