This NASA image of the day shows a multi-colored Mercury using color to enhance the differences between the rocks that make up Mercury’s surface.
Colors of the Innermost Planet
This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury’s surface.
