A team of researchers has made a groundbreaking discovery about the asteroid Bennu, shedding light on its surprisingly rocky composition. According to the study, Bennu's rocky nature can be attributed to its unique formation process. The asteroid is thought to have originated from a larger planetary body that was destroyed in the early days of the solar system. As a result, Bennu's surface is composed of a mixture of rocks and debris that were left behind after the destruction of its parent body. This discovery has significant implications for our understanding of the early solar system and the formation of asteroids like Bennu.

The researchers used data from NASA's OSIRIS-REx spacecraft, which has been orbiting Bennu since 2018, to make this discovery. The spacecraft's instruments have provided a wealth of information about Bennu's composition, shape, and size, allowing the researchers to piece together the asteroid's history. The study's findings suggest that Bennu's rocky composition is not unique,
