The rings of Saturn are the most extensive and complex ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, [1] that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material.
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as gas, dust, meteoroids, planetoids or moonlets and stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as of Saturn, or circumplanetary disks.
Rings of Rhea. 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.
Cassini–Huygens (/ kəˈsiːniˈhɔɪɡənz / kə-SEE-nee HOY-gənz), commonly called Cassini, was a space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites. The Flagship -class robotic ...
September 18, 2024 at 1:43 AM. Earth may briefly have had a ring system similar to Saturn ’s over 450 million years ago during a period of unusually intense meteorite bombardment, a new study ...
Saturn is probably best known for the system of planetary rings that makes it visually unique. [49] The rings extend from 6,630 to 120,700 kilometres (4,120 to 75,000 mi) outward from Saturn's equator and average approximately 20 metres (66 ft) in thickness.
The Phoebe ring is one of the rings of Saturn. This ring is tilted 27 degrees from Saturn's equatorial plane (and the other rings). It extends from at least 128 to 207 [20] times the radius of Saturn; Phoebe orbits the planet at an average distance of 215 Saturn radii. The ring is about 40 times as thick as the diameter of the planet. [21]
It is estimated that the A Ring contains 7,000–8,000 propellers larger than 0.8 km in size and millions larger than 0.25 km. [4] In April 2014, NASA scientists reported the possible consolidation of a new moon within the A Ring, implying that Saturn's present moons may have formed in a similar process in the past when Saturn's ring system was ...
