Moon craters tell the story of an asteroid that collided somewhere near Jupiter 800 million years ago. The fragments were flung towards the inner solar system, where they crashed into Earth, Mars, Venus and our Moon. Scientists say a 100km asteroid was the culprit.

China could soon outrival NASA in planetary defence and asteroid strike. Its new mission aims to slam an asteroid at a speed of Mach 26, much higher than the DART mission, and even break apart a small asteroid completely.  

China to whack asteroid at 26 times the speed of sound. Here's how the mission outrivals NASA's DART

A nearly 400-million-year-old crater has been discovered in Canada in an extremely rugged terrain that was extremely hard to reach. Scientists have confirmed that it is a meteor crash site, first seen on Google Maps by an amateur astronomer.

Asteroid 1998 SH2 managed to fool astronomers for nearly 30 years by its appearance and movement. But when it dodged a date with them in 2025, they knew something was wrong. Analysis showed that it was never an asteroid. 

Tracked by NASA since 1998, missing asteroid reappears as mysterious dark comet

Chinese scientists have proposed a deep detonation method to destroy a large asteroid posing a threat to Earth. According to a new paper, it would be best to dig a hole in the asteroid and then place the nuclear warhead for effective results.

Hayabusa2 probe has taken the closest photos of an asteroid ever. Japan Aerospace Exploration Agency's mission to Torifune was aimed at showing the preparedness in deflecting an asteroid in deep space. The asteroid flies nearly 100 million kilometres from Earth.

Probe carries out record flyby of asteroid 100mn km from Earth - 'It gave me goosebumps'

World Asteroid Day: Here is a list of asteroids flagged to pose a threat to Earth in the future. One of them is visiting this decade, while another is slated for early next year. Will they collide with Earth? Here are the details.

World Asteroid Day: Hazardous asteroids flagged to hit Earth and current status

Asteroid Day is observed on the anniversary of the Tunguska event in 1908. Earth has been hit by several asteroids in its history, but the most famous one remains the dinosaur killer. However, there are others that changed Earth in different ways.

An asteroid measuring over 3,300 feet is hurtling towards Earth at a speed of 32,000 kmph. Asteroid 1997 NC1 was discovered by the Near-Earth Asteroid Tracking system on Haleakala in Hawaii. Find out if the large asteroid poses a threat to our planet.

3,300-foot asteroid is racing towards Earth, and is the biggest in four years. Will it crash?

Earth crossed paths with an asteroid and missed an impact by a tiny margin of six hours. No one knew it was about to happen, and scientists detected it only nine days later. This scare led to the push for programs to watch for hazardous asteroids.

Earth dodged an asteroid by just 6 hours, crossing paths with a potential city-killer

Meteors rained down on Earth in April, and the source remained unclear. A study has now found a cluster of meteors which is possibly the culprit. There is a debris field and our planet is passing through it at the moment. We have a new meteor shower as well.

Scientists find source of March fireballs, reveal Earth is crossing a cosmic wake

Asteroid 2024 YR4 will miss the moon in 2032. Scientists have calculated that not only will it miss Earth, but it will also not collide with the moon anymore, an event that had a high chance of happening until recently. James Webb Space Telescope takes the honours.

Moon is safe - JWST pulls off near-impossible feat, locates asteroid that had gone into hiding

Two NASA scientists claim Earth is at risk from over 25,000 unknown asteroids that are yet to be discovered. If one of them moves towards the planet, no amount of preparation or a mission like DART would help.

25,000 hidden asteroids lurking near Earth pose major threat: NASA scientist says the fear 'keeps me up at night'

An asteroid impact would be devastating for Earth, but certain types of space rocks can be even more damaging, as, instead of breaking apart, they could become stronger. Scientists say this could have major implications for asteroid deflection missions.

Scientists reveal some asteroids could become even more lethal as they enter Earth

An asteroid spinning every 1.88 minutes has been discovered in the Asteroid Belt. Scientists are stunned to see the 2,300-foot rock going at such a fast speed. The discovery was made by the NSF–DOE Vera C. Rubin Observatory.

Asteroid spinning every 1.88 minutes is an anomaly because of its massive size

NASA has detected signs of a molecule that creates the happy hormone serotonin in an asteroid. Scientists have long believed these cosmic bodies brought life to Earth. Earlier analysis of Ryugu and Bennu has revealed several amino-acids.
