Scientists from the Southwest Research Institute have found strong evidence that near-Earth asteroids Bennu and Ryugu share a common origin with Polana, a much larger asteroid in the main belt. By ...

A groundbreaking study recently published in the Planetary Science Journalhas raised the possibility that asteroids Bennu, ...

A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the ...

Asteroid Ryugu’s Latest Mineral Is As Weird As Finding “A Tropical Seed In The Arctic” This discovery is making scientists question how this space rock came to be.

For the study, the researchers identified the mineral djerfisherite, which contains potassium, iron, and nickel, and surprised the researchers with its appearance as the presence of djerfisherite ...

A mineral that forms in hot, iron-rich conditions has been found in material from the asteroid Ryugu — which formed in cold conditions.

The surface chemistry of pyrrhotites from intact particles directly collected from asteroid (162173) Ryugu was investigated by micro-Raman spectroscopy. The Raman peak characteristic to pyrrhotite was ...

Samples of the carbonaceous asteroid (162173) Ryugu were collected and brought to Earth by the Hayabusa2 spacecraft. We investigated the macromolecular organic matter in Ryugu samples and found that ...

The family originated in the inner main belt not very far from the source regions of near-Earth asteroids (101955) Bennu and (162173) Ryugu, recently visited respectively by NASA's OSIRIS-REx and ...
