How many rings does each planet have and what is their composition?

Answer 1

Not every planet has rings! Officially, Jupiter has three (the Main, Halo and Gossamer rings,) plus a thin band of dust extending down to the cloud tops. Saturn has rings A, B, C, D, E, F and G, Uranus has 13 rings, named after Greek letters, and Neptune has five - four named after its discoverers, and one named the Plateau ring. Saturn's moon Rhea also seems to have a ring. It's important to realise that, for example, Saturn's rings are made up of thousands of tiny ringlets, so it's difficult to say where one "ring" begins and another ends.

Answer 2

There are four, all of the gas giants. The only planet with obvious rings is the planet Saturn. However, there are distinct and observable rings around Uranus (13, mostly ice) and Neptune (5, mostly dust), and there are tenuous ring filaments around Jupiter. The Jovian rings are the "Halo Ring", the "Main Ring" and the two-part "Gossamer Ring", associated with the moons Amalthea and Thebe. There are hypothetical dust rings around Mars, and it has been theorized that Earth may have had rings in the distant path that eventually dissipated.

Answer 3

the are 4 planets with rings in the solar system - Jupiter, Saturn, Uranus and Neptune.

Answer 4

Each of the four outer gas planets; Jupiter, Saturn, Uranus and Neptune have a ring system, but Saturns rings are by far the most spectacular.
