 Scientists
have ideas about why Saturn has rings, but no one knows for
sure.
What are Saturn's rings made of? Are they solid like the CD
you used to make your model? Or are they made of many
particles dancing in formation around the planet? Three
robotic spacecraft from Earth have already visited
Saturn--Pioneer 11, Voyager 1, and Voyager 2. They revealed
many surprising things about Saturn's rings.
The rings are about 400,000 kilometers (240,000 miles) wide.
That's the distance from the Earth to the Moon! But the
rings are as little as 100 meters (330 feet) thick. They
range from particles too tiny to see to "particles" the size
of a bus. Scientists think they are icy snowballs or ice
covered rocks.
There are actually many rings--maybe 500 to 1000. There are
also gaps in the rings. (That's why we put some black rings
on our model Saturns.) |
