What are Saturn's rings made of?
The rings comprise particles including rock particles, small bubbles and big chunks of ice. The particles reveal sparse hydrogen, oxygen and hydrogen monoxide.
Saturn ring system is thin and annular. It extend's (with gaps) around equator, from 7000 km to 80000 km.There are hundreds of rings divided into 8 groups. The second Cassini is as wide as 4000 km. It has a very large gap. All these and more might be either confirmed or revised, in the near future.
