P-21757 BW Range: 2 million kilometers (1.25 million miles) Jupiter's thin ring of particles was photographed by Voyager 2 on its approach to the giant planet. The spacecraft was 2.5° above the plane of the ring. Segments of both sides of the faint ring were captured in this picture. The ring was first photographed in an edge-on configuration by Voyager 1 and was measured then to have a radial extent of about 55, 000 kilometers (34,000 miles) from Jupiter's cloud tops. With this picture, it is possible to determine that the ring is much narrower radially than the individual rings of Saturn. T…
