Ring of Rocks on Bennu’s Boulder Spine

This image shows a partial ring of smaller boulders located in the midst of the long spine of boulders running down asteroid Bennu’s southern hemisphere. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on April 11, from a distance of 2.9 miles (4.7 km). The field of view is 217 ft (66.2 m). For scale, the long, thin rock located in the center of the upper part of the image is 23 ft (7.0 m) long, which is the length of a dump truck. The image was obtained during Flyby 6A of the mission’s Detailed Survey: Baseball Diamond phase. When the image was taken, the spacecraft was over the southern hemisphere, pointing PolyCam south and west.
