NASA's asteroid defence mission slowed targets just a bit

NASA's DART mission successfully demonstrated that a spacecraft collision can alter an asteroid's trajectory, with debris ejection doubling the impact's momentum and changing the binary system's orbital period by 0.15 seconds.

The moon is safe': asteroid is not on collision course, scientists confirm

Discovered in December 2024, asteroid 2024 YR4 was briefly considered the most dangerous asteroid in decades after scientists initially estimated it had a 3.1% chance of colliding with the Earth in 2032. Closer observations quickly ruled out a city killer scenario, but instead astronomers calculated there was a 4.3% chance that the moon lay in the path of impact.

Science

Notorious asteroid 2024 YR4 won't crash into the moon after all

Soon after it was spotted in December 2024, worldwide telescopic observations quickly positioned it as the most dangerous space rock ever discovered—one that stood a 3.1-percent (or 1-in-32) chance of crashing into Earth on December 22, 2032. If it were to hit one of the cities potentially in its path, this 60-meter asteroid would have unleashed a force comparable to several atomic bombs, devastating the unfortunate metropolis.

Aliens could be CATAPULTED onto Earth via an asteroid, study claims

We found that life is more likely to survive an asteroid impact, so it's definitely still a real possibility that life on Earth could have come from Mars. Maybe we're Martians! The idea that life could have spread through the solar system or even the universe on rocks is known as the lithopanspermia hypothesis.

Armageddon was RIGHT! We really could nuke asteroid heading for Earth

Nuclear detonations could deflect a metal-rich asteroid by nudging it, because some asteroid materials strengthen under intense impact rather than shatter.

Scientists Say Heck, Just Nuke a Killer Asteroid Heading for Earth

Plenty of asteroids can survive their fiery plunge through the Earth's atmosphere. If they're big enough, they can prove incredibly destructive, like the 60-foot Chelyabinsk meteor that exploded over the southern Ural region in Russia in 2013, releasing a blast equivalent to 30 times the energy of the atomic bomb that was dropped on Hiroshima. And in case an even larger space rock were to ever threaten humanity, we'd have to get creative to keep it from colliding with our planet.
