Astronomers can usually spot "planet killer" asteroids long before they approach Earth. But what if they can't?
A new study warns of an undiscovered population of asteroids that could strike Earth with little to no warning.
Asteroid 2024 YR4 currently has a 4% chance of smashing into the Moon in about seven years. Astronomers are already working out ways to prevent a potential impact.
Scientists still have much to learn about the potentially life-saving "kinetic impactor technique."
Asteroid 2024 YR4, which previously posed the highest impact risk to Earth ever recorded, has now been assessed a slightly higher chance of slamming into the Moon in seven years.
Dangerous rocks may co-orbit with Venus, but new research suggests only a space-based mission can prove it.
Astronomers have traced the origin of asteroid 2024 YR4, which appears to have broken off from a larger space rock.
New Webb Telescope data confirms that asteroid 2024 YR4 poses no threat to Earth during its 2032 flyby. As for the Moon, not so much.
2024 YR4 turned heads when it became the most dangerously rated asteroid earlier this week.
2024 YR4's odds jumped to a 1-in-32 chance of impact, though that number will likely fall as the asteroid continues to be monitored.
The odds of asteroid 2024 YR4 hitting Earth are shifting, with the space rock now carrying a 1-in-48 chance of collision.
Asteroid 2024 YR4 has a 2.2% chance of striking Earth in seven years, but recent updates keep pushing the odds in the wrong direction.
Bennu has a 1-in-2,700 chance of colliding with Earth in 2182, causing a global winter and drought.
A dive into probabilities, asteroid impact modeling, and what sort of damage an approximately 180-foot asteroid could cause on Earth.
The asteroid, designated 2024 YR4, jumped to the top of NASA's risk chart, with a slim but measurable chance of striking Earth in just seven years.
A new study posits that our planet's gravity will cause seismic activity on Apophis when it makes its close approach in 2029.
The potentially hazardous asteroid might be two space rocks fused together.
Nuclear devices generate massive amounts of X-rays. A new experiment suggests that might be enough to divert a killer asteroid.
Even if the one-in-a-billion situation were to happen, it wouldn't spell the end of humanity. Probably.
Rocks knocked off Dimorphos could come back to bite us in a few years—in the form of harmless meteors.
