On December 10th, the Dawn spacecraft began its closest orbit of Ceres. While passing just 240 miles from the surface of the dwarf planet’s southern hemisphere, a number of images were taken and are now arriving.
On December 10th, the Dawn spacecraft began its closest orbit of Ceres.
While passing just 240 miles from the surface of the dwarf planet’s southern hemisphere, a number of images were taken and are now arriving.
Among the pictures shared by NASA are those showing the celestial body’s craters and troughs.
Such features are often caused by impacts, but some are believed to be the result of tectonic forces occurring below the surface crust.
