Ancient solar system crash may explain Bennu and Ryugu’s origin

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 comparing James Webb Telescope observations with samples from NASA’s OSIRIS-REx and Japan’s Hayabusa2 missions, researchers discovered spectral similarities suggesting all three were once fragments of the same parent body, shattered in an ancient collision.
