This image taken by the Voyager 2 spacecraft of Saturn's A-ring shows the thin F-ring bracketed by its two shepherding satellites. Because the inner moon revolves around the planet slightly faster than the outer one, the satellites lap each other every 25 days. This picture was taken on August 15, 1981, when Voyager 2 was 10.5 million kilometers (6.6 million miles) from Saturn. At that instant, the shepherds were less than 1,800 kilometers (1,100 miles) apart. For higher resolution, click here.
