YR4, which orbits the sun every four years and periodically crosses Earth's orbit. The nature of its orbit makes it a ...

New observations of a small asteroid discovered in December have led astronomers to conclude that the chances of it striking Earth are almost zero after earlier data had indicated a higher risk of a ...

Analysis of samples brought back to Earth from the asteroid Bennu reveal that it has a bizarre chemical make-up and is ...

"Scientifically there's a huge amount we can learn from asteroids," says Alan Fitzsimmons, an astronomer at Queens University ...

The asteroid Bennu has been at the centre of scientific discussions recently, especially after researchers analysed surface samples collected by NASA’s OSIRIS-REx mission. While much of the ...

According to estimates, the asteroid, called 2024 YR4, had the highest chance of any asteroid to hit Earth in modern history.

YR4 has a very small chance of striking Earth when its orbit briefly intersects our planet's in December 2032.

New simulations reveal that the climate, atmospheric chemistry and even global photosynthesis would be dramatically disrupted by an asteroid collision ...

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 ...

It measures 130 to 300 feet across, a pebble compared to the asteroid that killed the dinosaurs, which is estimated to have been six to nine miles in length. On the other hand, on Feb. 15, 2013, an ...

Once, a very long time ago, a massive asteroid hit the Earth and wiped out the dinosaurs. In addition to functionally ...

For example, an asteroid estimated at 6-9 miles (10-15 km) wide - much larger than 2024 YR4 - hit ... of Bennu - with a diameter of roughly three-tenths of a mile (500 meters) - strikes Earth.
