Natural satellites throughout the solar system have many different surface features that include craters, mountains, valleys and maria, among many others. Explore surface features of the Moon and other natural satellites in the solar system, including craters, as well as other named features that often go overlooked. The dark maria, meaning seas, of our Moon are actually large relatively flat basalt plains that are volcanic in origin and are found mainly on the near side. Jupiter's moon Io is covered in volcanoes and flow features.
Search for features by type or by name, which is often a combination of a famous person or character and a Latin description of its feature type.
Plot the location of a natural satellite surface feature, determine its size and find out what body the feature is found on.
