PLANETS AND THEIR RINGS

The rings of Jupiter, Uranus, and Neptune are made of dust, very tiny pieces of rock, and ice. The rings of Saturn are made of large pieces of ice.

We don’t know for sure where these rings came from. In some cases, the rings have come from dust knocked off of the planets’ moons by meteorite bombardment, but some of them might have come from moons torn apart by the planet’s gravity, or they could have formed as the planets formed.



Saturn’s rings are the most magnificent; they are bright, wide, and colourful. Uranus has thirteen dark rings around it, and Neptune’s rings are also dark, but contain a few bright arcs.
