NASA is on high alert for a “city-killer” asteroid that’s headed toward Earth — cuz they don’t wanna miss a thing. The asteroid, called 2024 YR4, now has a 1.5% probability of hitting ...

Chilling animations depict the apocalyptic impact that "city-killer" asteroid YR4 2024 could have if it did hit Earth — while astronomers warn that the moon could be in the line of fire as well.

The Asteroid Terrestrial-impact Last Alert System (ATLAS) first spotted 2024 YR4 on December 27, 2024. At that point the asteroid was 515,116 miles (829,000 kilometers) from Earth.

The asteroid 2024 YR4 is now rated at Level 0 out of 10 on the Torino Impact Hazard Scale, meaning, "The likelihood of a collision is zero, or is so low as to be effectively zero.". A similar ...

Asteroid 2024 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 to see how much of a risk the space rock poses.

NASA will soon release the results of its DART mission to find out whether crashing a probe into a space rock can deflect it. Here’s how they'll do the math.

Even an asteroid on the smaller end of that range could have a big impact, depending on where it hit the Earth, says Lindley Johnson, NASA's Planetary Defense Officer Emeritus.

"An asteroid impact is one of the possible scenarios that we must be prepared for," Leviticus Lewis, ... This graph shows the total number of near-Earth asteroids discovered as of April 8, 2018.

The chances of asteroid 2024 YR4 colliding with Earth in 2032 hit a record high. Experts expect the risk percentage to fluctuate before likely dropping to zero. Here’s why.

A small asteroid crashed into Earth three years ago — and now scientists know where it came from. Researchers have traced the origins of the resulting rare meteorite fragments, which began the ...
