<P> The rings of Saturn are the most extensive ring system of any planet in the Solar System . They consist of countless small particles , ranging from μm to m in size , that orbit about Saturn . The ring particles are made almost entirely of water ice , with a trace component of rocky material . There is still no consensus as to their mechanism of formation ; some features of the rings suggest a relatively recent origin , but theoretical models indicate they are likely to have formed early in the Solar System 's history . </P>
