Janus (Natural Colors; credits: Lunar Explorer Italia)

Caption NASA:"Janus imitates its two-faced Greek god namesake by catching light on two sides. The brighter side of Janus is lit by the Sun while light reflected off Saturn dimly illuminates the rest of the moon and reveals the non-spherical shape of this small satellite.
