Rings of Saturn. The full set of rings, imaged as Saturn eclipsed the Sun from the vantage of the Cassini orbiter, 1.2 million km (¾ million miles) distant, on 19 July 2013 (brightness is exaggerated). Earth appears as a dot at 4 o'clock, between the G and E rings.
Saturn’s Rings: Young and Ephemeral, Three NASA Ames Studies Say.
8 de nov. de 2017 · Saturn's rings are made up of billions of particles ranging from grains of sand to mountain-size chunks. Composed predominantly of water-ice, the rings also draw in rocky meteoroids as they...
22 de set. de 2017 · Scientists have ideas about why Saturn has rings, but no one knows for sure. What are Saturn's rings made of? Are they solid like the CD you used to make your model? Or are they made of many particles dancing in formation around the planet? Four robotic spacecraft from Earth have visited Saturn—Pioneer 11, Voyager 1, Voyager 2 and ...
29 de ago. de 2005 · The rings of Saturn make up an enormous, complex structure that – from edge-to-edge – is wider than the distance from Earth to the Moon. The seven main rings are labeled in the order in which they were discovered; from the planet outward, they are D, C, B, A, F, G and E.

22 de mai. de 2023 · Three recent studies by scientists at NASA’s Ames Research Center in California’s Silicon Valley examine data from NASA’s Cassini mission and provide evidence that Saturn’s rings are both young and ephemeral – in astronomical terms, of course.
Cassini found that much of the material for Saturn's E-ring—a diffuse ring outside the bright, main rings—comes from the moon Enceladus, which is venting icy particles and gas into space as it orbits Saturn.
