A crescent Bennu NASA/Goddard/University of Arizona This image shows a top-down view of asteroid Bennu, with a portion of the asteroid's equatorial ridge and northern hemisphere illuminated. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on March 4, from a distance of about 186 miles. The image was obtained during the mission’s Post-TAG Operations phase, as the spacecraft slowly approaches Bennu in preparation for a final observational flyby on April 7.
