Scientists have simulated what would happen if asteroid Bennu, a 500-meter-wide space rock, were to collide with Earth in September 2182. The results paint a grim picture—global climate collapse ...

YR4, which orbits the sun every four years and periodically crosses Earth's orbit. The nature of its orbit makes it a ...

Asteroids the size of Bennu are believed to hit Earth every 100,000-200,000 years, so it is likely that our early ancestors have already survived one of these impacts. But what both Chicxulub and ...

Earlier this month, NASA revealed that samples collected from Bennu contain 14 of the 20 amino acids essential for life on Earth, as well as key organic compounds that play a role in forming DNA ...

An asteroid between about 130 and 300 ft. (40 and 90 meters) in diameter has been given a 2.3% chance of it hitting Earth on Dec. 22, 2032.

Bennu’s potential collision with Earth is a remote but unsettling possibility, according to a new study. Bennu is about 500 metres wide—taller than the Empire State Building and as wide as ...

YR4 has a 2.8% to 3.1% chance of hitting Earth in 2032. Astronomers are tracking it to refine estimates of its size and orbit ...

New observations of a small asteroid discovered in December have led astronomers to conclude that the chances of it striking ...

YR4 became the highest-rated asteroid predicted to strike Earth, and although predictions for impact have lowered, not enough ...

The asteroid Bennu is puzzling scientists ... NASA’s OSIRIS-REx spacecraft returned samples from the asteroid to Earth in 2023. They quickly found these contained a plethora of the chemical ...
