Early analysis of the asteroid Bennu sample returned by NASA's OSIRIS-REx mission has unveiled surprising insights into the early solar system and the potential origins of life on Earth.

However, many asteroids are known to be rubble piles, essentially collections of rocks held together loosely by gravity, such as the asteroid Bennu that was visited by NASA’s ORISIS-REx spacecraft.

A newly discovered asteroid has quickly shot to the top of ... There’s one called Bennu that is much bigger than 2024 YR4. There is a chance Bennu could strike in 2182, causing widespread ...
