If Bennu did hit Earth, it would trigger an explosion equivalent to 1.4 billion tons of TNT. Not only could the 500-metre-wide rock threaten millions of lives, but a recent study predicted that ...

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

A spacecraft's sample return capsule was detected entering the Earth's atmosphere using acoustic sensors by a team of scientists from the Los Alamos National Laboratory and Colorado State University.

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.
