How Many Rings Does Saturn Have?
What Is Their Interesting Story?
Saturn’s rings are one of the beautiful and also amazing spectacles of the solar system. That is why on July 1, 2004, the Cassini-Huygens spacecraft slowed down to be captured by Saturn’s gravity in order to enter orbit with it. We will answer the question: How many rings does Saturn have in this article?
Until 2008, the spacecraft will explore the planet, its mysterious moons, its narcotic rings and its complex magnetic environment. Cassini must make 74 rotations around the planet, approach Titan and other Saturn’s glacial moons. The most beautiful of the shows is when even Saturn’s rings are proposed to us, each one on orbit sound, totally aligned in a fine band of a few kilometers…
The origin of the rings
Saturn’s rings are made up of innumerable particles, each in a clean orbit, of silicates, various iron oxide and ice particles from a size of the dust grain to a few meters. Rings extend over a fine bed of more than 400,000 km. Except for the outermost ring, they do not exceed 1 km thick. All this matter gathered in a single object, would be equivalent to the size of Epimetheus, or Prometheus, that is, no larger than the moon from 100 to 150 km in diameter.
Proposed the theory by Édouard Albert Roche to the XIX century, explains that the rings come from Saturn’s moon whose orbit would have come too close to the planet and which would have been torn to pieces by tidal forces or disintegrated by the impact of a comet or asteroid. Saturn’s rings are too unstable to last, so they have a recent origin on the astronomical scale.
A complex system
Saturn’s rings maintain complex resonances with some of its satellites. Surely, named ‘shepherd satellites’ (Atlas, Prometheus, and Pandora), are genuinely essential to the stability of the rings. Mimas seems responsible for the Cassini division, Faldon is located within the Encke division. The global system is very complex, as shown by the results of the Cassini probe, entered into Saturn’s orbit in 2004. This complex and amazing planetary system intrigues scientists. Of these intrigues concerns the Cassini division, that is, the large interval between rings A and B. While Saturn’s rings are almost exclusively made up of water in the form of ice, the data show that the Cassini division contains more dust than ice. Discovered the Cassini division in the 17th century by Giovanni Doménico Cassini, it revealed that Saturn’s rings did not constitute contiguous elements. The particles between rings A and B closely resemble what you have observed on Phoebe, one of Saturn’s moons.
The Rock Limit
What you need to consider is the proximity of the rings relative to your planet. In effect, the area of the rings is only between 60 and 200,000 km from the planet, so Saturn has an equatorial diameter of 120,536 km. Which explains the instability of its ring structures.
Its particle structures can thus exist only within a well defined perimeter within the Rock boundary maintained by the strong attraction of the nearby planet. Near the planet, the attractive forces of the planet on two nearby particles is greater than the mutual attraction between the two particles, which prevents the accretion of the particles. The distance at which these two effects cancel each other is called the Rock limit.
Furthermore, the collisions cause the particles form by accretion process and to form a satellite. The origin of the rings remains one of the most difficult problems for astronomers. Even more so when it is not a unique phenomenon. Jupiter, Uranus, and Neptune also have comparable ring systems. From Earth this structure appears homogeneous, but closer the rings show different bands. Closer still, we would see countless and free particles that would disappear very quickly if no mechanism keeps them in place. This is where the guardian satellites collect on the track. This role of the sculptor and guardian of these structures is mainly played by these satellites. Saturn’s rings are less than a kilometer thick and can locally be much thinner. Indeed, collisions tend to reduce movements perpendicular to the equatorial plane. The natural shape of a ring is therefore to be flat and wide, regularly shown up to the limit of Roca. All objects that leave this area become a satellite. The origin of the rings remains one of the most difficult problems for astronomers. Even more so when it is not a unique phenomenon. Jupiter, Uranus, and Neptune also have comparable ring systems.
From Earth, we can see three rings, the rings (A and B) and a finer ring. The zone between A and B is known under the name of Cassini division. Ring A is divided by a less visible space called the Encke division. Voyager probes have detected four other much less visible rings.
Ring F, one of the outermost, has an extremely complex structure of several smaller interlocking rings. The origins of those knots are unknown but are probable gravitational
Ring E, the outermost, extends over 300,000 km and progressively widens after Encelade’s orbit to reach 60,000 km thick. Note: Saturn’s equatorial diameter is 120,536 km
. These black particles re-launch the theory that the rings would be the remains of the disintegrated moon. The Cassini probe detected large amounts of oxygen at the ring entrances.
This phenomenon might also were explained by means of a
collision that would have triggered this sizable oxygen separation.
