On and beneath its pitch black surface, Bennu may contain chemicals and rocks from the birth of the solar system. Plus, at 510 meters (1,673 feet) from pole to pole, Bennu is suitably large for an ...

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

Highly porous rocks responsible for Bennu's surprisingly craggy surface Date: October 6, 2021 Source: University of Arizona Summary: Using data from NASA OSIRIS-REx mission, scientists concluded ...

Why is Bennu spitting rocks into space? This is one of the weirdest things it does, and that’s saying something. Bennu is a small asteroid, only a little over 500 meters wide. It’s shaped like ...

Highly porous rocks responsible for Bennu's surprisingly craggy surface Using data from NASA OSIRIS-REx mission, a University of Arizona-led team of scientists concluded that asteroids with highly ...

A near-Earth asteroid named Bennu has a loosely packed surface similar to a pit of plastic balls, according to NASA scientists. A spacecraft collected a sample from the asteroid in October 2020 ...

New research reveals veins of carbonite materials in Bennu's boulders, as well as signs of organic minerals widespread across its surface. The variety of rock compositions on the asteroid's ...

Bennu isn’t a cold, dead rock after all. NASA’s OSIRIS-REx spacecraft has spotted the asteroid spewing out dust and rocks on 11 separate occasions over a period of just a few weeks, which was ...

Asteroid Bennu, which could provide answers to questions about the origins of our solar system, is mysteriously launching particles into space and NASA isn't sure why. Since reaching the massive ...

While the average rock has a density of about 3,000 kilograms per cubic meter, Lauretta says, the surface material on Bennu has a bulk density of about 500 to 700 kilograms per cubic meter.

However, most of Bennu is composed of rocks containing water-bearing minerals, so it (and its parent) couldn’t have experienced very high temperatures. Next, the team considered localized ...

An enormous asteroid that could one day hit Earth in a devastating impact is mysteriously spitting out rocks. So-called “doomsday” asteroid Bennu is ejecting meter-sized “particles” into ...
