Cylindrical projection maps of Bennu’s surface: geographic distribution of the two groups (grey and orange) obtained at a 2.7σ confidence level (top), map of the surface with craters and features generated from mosaicked V-band images as described by DellaGiustina et al. (2019) (center), and geographic distribution of the five groups obtained at 2.0σ confidence level (bottom). White dots indicate data that are not available or not classified.
