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.
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]
Fainter planetary rings can form as a result of meteoroid impacts with moons orbiting around the planet or, in the case of Saturn's E-ring, the ejecta of cryovolcanic material. [ 5 ] [ 6 ] Ring systems may form around centaurs when they are tidally disrupted in a close encounter (within 0.4 to 0.8 times the Roche limit ) with a giant planet.
Saturn’s moons Dione, Enceladus and Tethys dot the left side, while the Cassini division, Encke gap and rings A, B, C and F are shown on the right side. The Cassini division is the largest of ...
The Day the Earth Smiled. Earth can be seen as a blue dot underneath the rings of Saturn. The photomosaic from NASA's "Wave at Saturn" campaign. The collage includes some 1,600 photos taken by members of the public on The Day the Earth Smiled. The Day the Earth Smiled is a composite photograph taken by the NASA spacecraft Cassini on July 19, 2013.
List of nearest exoplanets. Fomalhaut b (Dagon), 25 light-years away, with its parent star Fomalhaut blacked out, as pictured by Hubble in 2012. [ 1] In 2020 this object was determined to be an expanding debris cloud from a collision of asteroids rather than a planet. [ 2] There are 7,026 known exoplanets, or planets outside the Solar System ...
J1407b is a substellar object, likely unbound to any star, with a dusty circumplanetary disk or massive ring system.It was first detected by telescopes of the Super Wide Angle Search for Planets (SuperWASP) and All Sky Automated Survey (ASAS) projects in April–June 2007, when J1407b's disk eclipsed the star V1400 Centauri and caused it to undergo a series of dimming events for 56 days.
An annotated picture of Saturn 's many moons captured by the Cassini spacecraft. Shown in the image are Dione, Enceladus, Epimetheus, Prometheus, Mimas, Rhea, Janus, Tethys and Titan. The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan, which is larger than the planet Mercury ...
