Peggy is the informal name for a former moonlet in the outermost part of Saturn's Ring A, orbiting 136,775 kilometres (84,988 mi) away from the planet. The moonlet was discovered by the Cassini Imaging Team in 2013 and it may likely be exiting Saturn's A Ring. [1] No direct image of Peggy has ever been made. [4]
A failed photopolarimeter prevented Voyager 1 from observing Saturn's rings at the planned resolution; nevertheless, images from the spacecraft provided unprecedented detail of the ring system and revealed the existence of the G ring. [28] Voyager 2 ' s closest approach occurred in August 1981 at a distance of 41,000 km (25,000 mi). [27]
Saturn has the most spectacular ring system, with seven rings and several gaps and divisions between them. Few missions have visited Saturn: Pioneer 11 and Voyagers 1 and 2 flew by, but Cassini ...
NASA's Cassini spacecraft sent back images looking over the shoulder of Saturn's rings. See more on Saturn's rings: No telescope on this planet would ever have been able to see this.
An artist's impression of Rhea's rings. The density of the particles is exaggerated greatly to aid visibility. [1] Rhea, the second-largest moon of Saturn, may have a tenuous ring system consisting of three narrow, relatively dense bands within a particulate disk. This would be the first discovery of rings around a moon.
The Hubble Space Telescope captured a newly revealed image of the mysterious, ghostly shadows on Saturn’s rings — the latest sighting of the so-called “spokes” that continue to baffle ...
Porco was the first person to describe the behavior of the eccentric ringlets and the "spokes" discovered by Voyager within the rings of Saturn; to elucidate the mechanism by which the outer Uranian rings were being shepherded by the Voyager-discovered moons Cordelia and Ophelia; and to provide an explanation for the shepherding of the rings ...
