Detailed View of Bennu’s Prime Meridian Boulder

This image shows details of asteroid Bennu’s prime meridian boulder, which is located in the southern hemisphere. A shadowed shelf in the boulder’s northwest face can be seen on the left. The image was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on July 16, from a distance of 0.4 miles (0.7 km). The field of view is 31 ft (9.5 m). For scale, the shadowed ledge on the left is 19 ft (5.7 m) long, which is about the length of a full-size pickup truck. The image was obtained during the mission’s Orbital B phase. When the image was taken, the spacecraft was over the southern hemisphere, pointing PolyCam straight down.
