Voyager 2 image, tinted pale blue, showing the planet Neptune's two major rings. The rings have radii of 53,000 km and 63,000 km and are composed of microscopic dust particles. They are narrow and contain clumps and kinks thought to be associated with tiny shepherd" moonlets, too small to be detected directly. Similar narrow, dusty, braided rings have been detected around Saturn (the F-ring & Enke Gap ringlet) and Uranus (1986U1R). The image was obtained as the Voyager spacecraft was leaving the Neptune system on 26 August, 1989, from a distance of 1.1 million kilometres."
