Close-up image of Methone, a small moon of Saturn, showing a smooth icy surface

Methone, Saturn’s small moon, shows no craters larger than 130 meters

Audio narration · Coming soon

Cassini's close observation of Methone, a small moon of Saturn about three kilometers across, revealed no craters larger than 130 meters. This smooth surface suggests Methone has an extraordinarily porous icy composition that may cause its surface to shift and erase impact scars over time.
