What are Saturn's Rings made of?
These rings are made from pieces of ice - ranging in size from microscopic dust to large boulders. The rings of Saturn is about 100 meters thick. The gap in the A-ring (at the top left of this photo) is called the Encke Division. A shepherding satellite (1980S27) of the F-ring is visible at the top of this photograph by Voyager 2.

Why is Mars red?
Because it's rusty!
Pictures from the Mars Pathfinder mission showed that there are lots of rocks on the surface of Mars. Pathfinder's Sojourner rover examined these rocks and found iron in them. Also, a dozen Martian rocks have been found here on Earth - they fell from the sky as meteorites. Those rocks have iron in them too. [...] suppose that it gets warm and wet on a planet... warm and wet enough for there to be water in the atmosphere for awhile, or maybe even water on the surface. If that happens, rocks that have iron in them can change. This change is called weathering and it can be brought about by water. Pure iron weathers to make rust. And iron-rich rocks can weather to make reddish, rust-like minerals [...] It's one of the reasons we think there could have once been life on Mars.

How big are the Sun, Planets and Moon in Comparison?
Earth seems to us like a pretty big place. Well, Jupiter has 317 times more mass than Earth! Saturn is 95 times as massive as Earth. But even with those giants hogging all that mass, the Sun contains 99.86% of the mass of the entire solar system!
