Why do some planets have rings?
The rings of Saturn are magnificent. They are bright, wide, and colourful. Uranus has nine dark rings around it. Neptune's rings are also dark. The rings of Jupiter is thin and dark.
Scientists have not come to an agreement on the origin of these rings. The rings may have formed from the dust knocked off the planet's moons when they were bombarded by meteoroids. Some of them might have come from moons torn apart by the gravity of the planet, or they could have formed as the planet's formed.
The rings of Jupiter, Uranus, and Neptune are made of dust, and very tiny pieces of rock and ice. The rings of Saturn are made of large particles of ice.
