1, 2, 3 Bennu!

This set of PolyCam images shows Bennu getting larger in the camera’s field of view as the OSIRIS-REx spacecraft continues its approach toward the asteroid. The images represent Bennu at 1.09 pixels, 1.71 pixels and 3.75 pixels, and were obtained on Oct. 13, 14 and 15, respectively. From the first to the last image, OSIRIS-REx’s range to Bennu decreased from around 20,720 miles (33,350 km) to around 6,060 miles (9,750 km). The images are cropped and processed.
