Thickness of Mercury

Model of the crustal thickness of Mercury. Gravity and topographic data obtained by NASA’s MESSENGER spacecraft are used to estimate the current thickness of Mercury’s crust, with shades of red and white indicating thick crust and shades of blue are thin crust. Orthographic projection is centered on 120°E longitude and the Caloris basin is in the upper right. (Smithsonian Institution)
