As NASA’s OSIRIS-REx probe starts to really close in on its target, scientists here on Earth have made a surprising discovery about the asteroid Bennu. Newly published research describes how the ...

In order to understand Bennu's rotation, scientists studied data of the asteroid taken from Earth in 1999 and 2005, along with data taken by the Hubble Space Telescope in 2012.

On a distant space rock being explored by a NASA probe, days are slowly shortening — and scientists are still trying to figure out why. Right now, the asteroid known as Bennu is spinning once ...

On October 20, NASA’s OSIRIS-REx spacecraft will briefly touchdown on the near-Earth asteroid Bennu and attempt the agency’s first sample collection from an asteroid that will be returned to ...

The asteroid Bennu has been full of surprises since NASA’s OSIRIS-REx arrived to orbit it in December 2018. In six weeks, ... Bennu completes a rotation every 4.3 hours, ...

In order to understand Bennu’s rotation, scientists studied data of the asteroid taken from Earth in 1999 and 2005, along with data taken by the Hubble Space Telescope in 2012.

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 ...

Yesterday, NASA’s OSIRIS-REx spacecraft passed by the asteroid Bennu for the last time, ending its two-and-a-half-year relationship with the space rock.

It's not an unknown phenomenon, but it is rare, and scientists only confirmed their first example of an asteroid's rotation speeding up in 2007. Even at Bennu , the observations leave the mystery ...

The new research finds the asteroid’s rotation is speeding up by about 1 second per century. In other words, Bennu’s rotation period is getting shorter by about 1 second every 100 years.
