Ceres' water ice may hide huge salt deposits on its surface

Ceres holds between 25 and 30 percent of the total mass of the main asteroid belt, and it is the largest object in that belt. Water ice on the dwarf planet's surface can mask massive salt deposits, according to the source. Ceres carries the same dwarf planet label as Pluto, yet it is often treated as an asteroid because of where it orbits.
