Ring particles of Jupiter and Uranus also show this behavior. Then those theories had to be revised to account for the rings of Uranus. The revisions implied that Jupiter would not have a ring. Now Jupiter has been found to have a ring and we have to invent a theory to explain it. The ring structure the Voyagers discovered is too complex to … explain thousands of rings.
They had run out of resonances long ago.
As originally conceived, shepherd moons were supposed to corral ring particles, keeping entire ring systems together over eons. Rings are no longer viewed as debris from the solar nebula with an age of billions of years. Nevertheless, shepherd moons continue to be presented as the reason planetary rings exist. Therefore, rings must be simultaneously decaying, yet confined by shepherds:. Saturn has a very intricate ring system with lots of moons helping to keep its rings together.
As mentioned above, the last two are now viewed primarily as rapidly decaying, despite putative shepherding effects. During the Saturn ring plane crossing, the Hubble Space Telescope looked for new satellites. Two were announced as new in a press release and were designated S1 and S2. A stunning observation answered this question.
The reason the previously mentioned satellite S2 was not initially recognized as Prometheus is that its location did not match the position expected. It is doubtful that the so-called shepherds of the F ring ever fulfilled that function. Instead, Prometheus and Pandora are fragments of larger bodies en route to further disintegration, the same process thought to have produced the moonlets S3 to S7.
Prometheus and Pandora are not spherical and have an irregular shape.

The F ring itself is expected to widen over time, eventually dissipating altogether. The Voyager missions demolished the belief that planetary rings must be old. The Cassini probe began orbiting Saturn in The resonance theory was invoked to prevent such downward revision, but failed to counter indications that planetary rings are much younger than the conventional age of the solar system. The shepherd moon theory continues to be employed to minimize the downward revision. This demonstrates amazing consistency with the biblical model because it shows the rings are young and only recently formed.
It also opens up plausible explanations within the model of how the rings formed, e. We have supplied this link to an article on an external website in good faith.

Fun Facts about the Planets for Kids. The name Saturn is derived from the Roman God Saturn; he was god of fertility and agriculture. How big is Saturn? How far is the planet Saturn away from the Sun? Saturn is recognizable because of its rings. Saturn's rings were discovered by Dutch astronomer Christian Huygens in and the bright interior ring is named the Huygenian region in tribute to him, however the true structure of the rings was not determined until the 19th century.
The rings around planet Saturn measure around , km in diameter and have a depth of around only 1km.
Physical characteristics of Saturn
What is it like on the surface of the Planet Saturn? The atmosphere has a few streaky clouds and very high winds; the wind speed can reach a whopping 1, km per hour! Does the planet Saturn have any moons? Saturn's largest moon is called Titan.
It is an extremely light planet as it has no density, in fact if you could find an ocean big enough to drop the planet into, it would float! Saturn, Jupiter, Uranus and Neptune are mainly made up of gases; collectively they are called the outer planets. Saturn orbits the sun once every 10, Earth days which is equal to once every The rings are structured from thousands of smaller rings called ringlets, the two outer ropes twist around each other similar to the structure of rope.
