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 ...

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

and NASA has since calculated there is a 0.037 per cent – or one in 2,700 – chance that the asteroid will strike our planet on September 24 2182. If Bennu did hit Earth, it would trigger an ...

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.

For example, an asteroid estimated at 10 to 15km wide - much larger than 2024 YR4 - hit off the ... asteroid the size of Bennu - with a diameter of roughly 500m - strikes Earth.

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