ScienceSaturn's Moon Methone Has No Craters Larger Than 130 Meters
Cassini's close observation of Methone, a tiny moon of Saturn about three kilometers across, revealed no craters larger than 130 meters. Its porous icy surface likely erases impact scars over time, and Saturn’s tides along with the moon’s rotation shape it into a smooth, egg-like form. This suggests a surface that cannot easily preserve relief features.
