Epimetheus up close (from about 74.600 Km) but in false colors
Caption NASA originale:"The color of Epimetheus in this view appears to vary in a non-uniform way across the different facets of the moon's irregular surface. Usually, color differences among planetary terrains identify regional variations in the chemical composition of surface materials. However, surface color variations can also be caused by wavelength-dependent differences in the way a particular material reflects light at different lighting angles. The color variation in this false-color view suggests such "photometric effects" because the surface appears to have a more bluish cast in areas where sunlight strikes the surface at greater angles. The slightly reddish feature in the lower left is a crater named Pollux. The large crater just below center is Hilairea, which has a diameter of about 33 Km. At 116 Km across, Epimetheus is slightly smaller than its companion moon, Janus (181 Km across), which orbits at essentially the same distance from Saturn".
