The comet C/2022 E3 or ZTF will pass nearest to the Earth on 1 February. It is believed to have come from the Oort Cloud, a theorised vast sphere surrounding the Solar System that is home to mysterious icy objects. Some experts say the ZTF will never return to Earth again

Explained: How 3 tiny dust specks reveal the secrets of asteroids

The three minute particles from an asteroid called Itokawa show some of these space rocks are vastly older than was thought, and are much tougher. According to new research published, this could imply that we need bolder ways to prevent catastrophic collisions with Earth

Jurassic Park: What the world would look like if dinosaurs hadn't gone extinct

The catastrophic event in which an asteroid struck the Earth and killed over 90 per cent of all species, including dinosaurs, allowed for human evolution

BAM! NASA spacecraft Dart rams asteroid Dimorphos in defence test

The $325 million mission was the first attempt to shift the position of an asteroid or any other natural object in space

Explained: NASA's 'save the world' experiment which will see a spacecraft crash into an asteroid

NASA plans to crash a small, harmless asteroid millions of miles away. The aim is just to nudge the asteroid into a slightly tighter orbit around its companion space rock — demonstrating that if a killer asteroid ever heads our way, we'd stand a fighting chance of diverting it

Asteroid, bigger than Empire State Building, heads towards Earth; all you need to know

The asteroid is bigger than most buildings on Earth, including the Statue of Liberty, the Eiffel Tower and the Empire State Building

Meteorites that helped form earth may have formed in outer solar system, suggests study

In this study, a combination of asteroid observations suggests that the surface minerals present on outer main-belt asteroids, especially ammonia-bearing clays, form from starting materials containing NH3 and CO2 ice that are stable only at very low temperature, and under water-rich conditions

Asteroid twice the size of Burj Khalifa to fly past Earth; NASA shares link to track it live

Reports suggest that asteroid 1994 PC 1 has been classified as ‘potentially hazardous’ by NASA because of its closeness while shooting past the Earth

NASA aims to defend the planet by using its DART mission to destroy an asteroid this month

The target asteroid, Dimorphos, which means "two forms" in Greek, is about 525 feet in diameter and orbits around a larger asteroid named Didymos, "twin" in Greek.
