These mosaics of the icy satellites show the satellites at the same scale and with approximately natural colors and brightness. This allows the viewer to compare the satellites directly. For example, most of the Galilean satellites are distinctly brighter than Earth's Moon. Callisto is much darker than Io or Europa, but Triton is exceptionally bright due to the presence of frosts and ices. Image processing of these mosaics by Timothy J. Parker (JPL).
