Very little is known about poor Pan, the nearest satellite to Saturn. It is a shepherd moon in the Encke Gap of Saturn's A ring. A shepherd moon limits the extent of a ring so Pan keeps this gap open through its gravitational effects. It was discovered by studying imagery from the Voyager 2 probe. See also: rings of Saturn.
