The "F-Ring", alone

Caption NASA originale:"Zigzagging kinks and knots dance around Saturn in the F-Ring. From a great distance, as during Cassini's initial approach to Saturn in mid-2004, the F-Ring appears as a faint, knotted strand of material at the outer fringe of Saturn's immense ring system. From this close vantage point, just after the spacecraft rounded the planet to begin its second orbit, the F ring resolves into several ringlets with a bright central core. The core of the F ring is about 50 Km wide and is located at a distance of approximately 80.100 Km from Saturn's cloud tops".
