By the way, though they are a lot more difficult to see, Uranus, Neptune and Jupiter also have rings; Cornell’s astronomers had quite a hand in the discovery of Jupiter’s ring system.Astronomy is our oldest science, and the heavens are an almost unending source of questions for us all. This 2004 photo provided by NASA, taken by the Cassini Saturn Probe, shows planet Saturn and its rings. Support for the CCMR is provided through the NSF Grant DMR-1719875, part of the NSF MRSEC Program.Additional support is provided by Cornell University, the State of New York, and by industrial sources.Cornell Center for Materials Research | An NSF MRSEC The pieces all “connect” with each other, rather weakly, making a mobile fluid-like disk (actually Saturn has several identifiable ring systems). It’s a truly beautiful planet made particularly so by its ring system. So, it seems that they are not like the sort of thick-circle you might get by cutting a solid ring-like section out of a frisbee, and having it rotate around a ball at the center which would represent the planet itself. Beyond that are two far fainter rings named G and E.The particles in Saturn's rings are composed primarily of water ice and range from microns to metres in size.
Imagine if we took our moon, broke it up into a huge number of small pieces, and then spread these into a ring system.
It would therefore be pretty hard to say that the rings were one solid object, if we could see through them! 3. Saturn's rings are ringing like a bell, which is making it possible for researchers to explore deep inside the heart of the planet. They appeared to him as 'ears' or lobes either side of the planet. Saturn’s rings have remained one of the most evocative mysteries of the solar system. The main rings are, working outward from the planet, known as C, B, and A.The 'Cassini Division' is the largest gap in the rings and separates Rings B and A (named after Jean-Domenique Cassini who discovered the gap in 1676).In addition a number of fainter rings have been discovered more recently. Materials from the CCMR website may not be used without permission. Saturn also has 22 moons and they are also known to assist in keeping the ring system stable.
Saturn’s rings are made up of separate ice and rock particles.
... gas giants have no solid surface to measure such waves. Instead, they’re made of dust, gas, ice, and small rocks. So, it seems that they are not like the sort of thick-circle you might get by cutting a solid ring-like section out of a frisbee, and having it rotate around a ball at the center which would represent the planet itself. It would therefore be pretty hard to say that the rings were one solid object, if we could see through them! But, while the particles in each ring do move at high speeds, this motion, like the motion of the dark areas on the spinning paper, is not why the rings appear solid. 2. The materials in the rings are very small and scattered over great distances. Well, this doesn’t necessarily say that the rings are made of chunks of cold, solidified hydrogen, but it’s interesting that we now know their composition to be mainly ice, that is, solid water; and as you may have learned by now water (or H2O) is two-thirds hydrogen.So ice-particles (some are big, around a few meters in size) are what mostly form the rings in which small quantities of other materials are also present. It’s a good question; and a very long-standing one.You and your classmates may have seen the spectacular show being put on by Mars, which is closer now to our Earth than it will be for quite some time to come. From Earth, the rings look solid, but up close, they are translucent bands made of countless particles, mostly ice, some rock. The rings show a tremendous amount of structure on all scales; features like spokes and irregular ripples, are puzzling. This question can be asked for any disk-like phenomena that occur in space.
From earth it looks solid but it is very thin.You can see bright stars through it.The comet tails are millions of kilometers long but total matter may be few tons only. Why are Saturn's rings in a perfectly flat circle? (You may have noticed that it’s much in the news these days as a possible energy source.) You can probably see that your question is leading us to other important questions, such as, what are the pieces actually made of, how thick overall are the rings, and why are the rings flat anyway?The reason for mentioning Saturn’s position in our planetary system is that along with Jupiter we have a pair of planets that between them account for around 90% of all the matter we have in all ten of our planets. Why are the ice particles not spread out all around the planet? Compared with the size of the planet we know the rings must be very, very thin because Saturn (and its rings) rotate and occasionally the rings are presented to us ‘edge on’ and they are very hard to see (imagine how this must have puzzled Galileo when he looked back later and could not see the striking features that made Saturn so prominent to him in the first place). Jupiter and Saturn are often called “Gas Giants” simply because they are largely made from the most abundant element in the Universe. The F Ring is a narrow feature just outside the A Ring.
