A sample from asteroid Bennu contains organic compounds usually found at midocean ridges on Earth, suggesting Bennu may have been part of an ancient ocean world.

Five science instruments mapped Bennu's chemistry and mineralogy to determine the effect of sunlight on the asteroid's orbit. Cost of the mission, excluding launch, is $800 million.

Asteroid Bennu is a potentially hazardous near-Earth asteroid that was studied by NASA's OSIRIS-REx mission from 2018 to 2021.

Now, don’t get me wrong. Bennu isn’t an asteroid that will bring about worldwide devastation. If the asteroid were to collide with Earth, it would damage the planet outward up to 600 miles ...

Bennu is a 1,600-foot-wide near-Earth asteroid that was discovered in 1999 by the Lincoln Near-Earth Asteroid Research (LINEAR) Project. It passes by Earth approximately every 6 years. However ...

NASA’s OSIRIS-REx asteroid probe has spotted the asteroid Bennu flinging pieces of its own surface into space. These “particle ejection events” happen all the time, … ...

In 2018, the OSIRIS-REx mission arrived at the near-Earth asteroid Bennu to collect pristine samples, untouched by alterations induced by Earth's atmosphere, to be analyzed on Earth.

This asteroid is one of the most likely to hit Earth. Here’s what it means for our future. New ultraprecise measurements show that the asteroid Bennu has a higher chance than thought of ...

An early analysis of a sample collected from the asteroid Bennu suggests that the space rock had an unexpectedly water-rich past — and it may have even splintered off from an ancient ocean world ...
