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]
Most people will require an optical aid (very large binoculars or a small telescope) that magnifies at least 30 times to achieve an image of Saturn's rings in which a clear resolution is present. [ 49 ] [ 151 ] When Earth passes through the ring plane, which occurs twice every Saturnian year (roughly every 15 Earth years), the rings briefly ...
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.
Saturn’s rings are seen as viewed by NASA’s Cassini spacecraft, which obtained the images that comprise this mosaic at a distance of approximately 450,000 miles from Saturn April 25, 2007.
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 ...
Hyodo said it's possible Saturn's rings could be somewhere between the two extreme ages — around the halfway mark of 2.25 billion years old. But the solar system was much more chaotic during its formative years with large planetary-type objects migrating and interacting all over the place, just the sort of scenario that would be conducive to ...
The innermost large moons of Saturn orbit within its tenuous E Ring, along with three smaller moons of the Alkyonides group. Mimas is the smallest and least massive of the inner round moons, [ 44 ] although its mass is sufficient to alter the orbit of Methone . [ 52 ]
See more on Saturn's rings: No telescope on this planet would ever have been able to see this. Cassini left Earth in 1997 and, in its nearly two decades of exploration, has sent home remarkable ...
