"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said.

The stadium-sized asteroid 2020 XR is due to make its closest approach to Earth on record early on Dec. 4, and the encounter will be livestreamed for everyone to see.

On Sunday, NASA’s OSIRIS-Rex mission will deliver a sample it collected from asteroid Bennu, completing a seven-year journey that could provide insights into how life originated on Earth.

The $10 billion orbiting observatory will give astronomers a better sense of the near-Earth asteroid 2024 YR4's size and position.

A recently discovered asteroid, named 2024 YR4, has on average a 2% chance of hitting Earth in 2032.

Radiation should be able to deflect asteroids as large as 4 km across Researchers blast silica with an intense X-ray burst, watch it evaporate.

For a PHA, a measurement of 22 or under means the asteroid must be at least 500 feet (140 meters) across.

The asteroid’s closest approach to Earth, it turned out, had been two days earlier, when YR4 was about 800,000 kilometers from our planet, roughly twice as far away as the moon.

New research suggests that the asteroid responsible for forming Earth's largest impact crater was even bigger than researchers had previously estimated.

NASA retrieved a sample from an asteroid for the first time, providing scientists with material to understand the early origins of the Solar System.

The odds are about 1% that the football field-sized object could hit the Earth, but that makes it the closest call in more than 20 years.
