Saturn

Saturn's Beautiful Rings
Saturn is the second largest planet in the solar system, it is a gas giant as well. Saturn's atmosphere is made mostly of Helium, making it extremely light. If you had an ocean large enough to put Saturn in, it would float. Saturn is famous for it's rings. (even though Uranus, Neptune and Jupiter also have rings) Saturn's rings are made mostly of ice, which makes them so bright. It is still unknown how Saturn's rings formed. Most scientists believe that a moon was ripped apart and the pieces continued to orbit Saturn, thus, forming it's ring. The planet takes about 10,759 Earth days, or about 29 1/2 Earth years, to go around the sun.

Jupiter

The Great Red Spot
Jupiter is the largest planet in the solar system. It is also a gas giant, a group of 4 planets made almost compeletly of gas. Jupiter has many moons (over 60). One of it's moons, Europa, has a liquid ocean underneath it's icy surface. Jupiter fas a large storm that has been there for at least 50 years known as the great read spot, it is over 100 times stronger than a hurricane. Jupiter has a very thin ring that is not easily seen and has the strongest magnetic field in the whole solar system and often has ultra violent auras at it's poles. It would take 1,00 Earths to fill Jupiter up. It has a diameter of 88,846 Miles. It takes 4,333 Earth days to orbit or almost 12 Earth years.

Comets

The Comet Hyakutake
Comets are dirty balls of ice and dust that form in the outer solar system. They usually have an elliptical or oval orbit. When They get close to the sun their gases start melting and streaming behind them in a beautiful tail that glows brightly. Comets are believed to come from a region beyond Pluto called the Oort Cloud. Comets are believed to have brought water to Earth in the form of ice on comets.

Asteroids

Asteroids are blocks of space debris. They are usually made of iron, rock and other metals. Most asteroids orbit in a belt inbetween Mars and Jupiter in an area known as the Asteroid Belt. This is considered the divider between the inner and outer solar system. Asteroids are basicly failed planets that couldn't come together to form a planet.

Mars

Mars is often called the red planet due to it's rusty rocks that make a red glow. Mars is roughly half the size of Earth and has ice at it's poles. It has the highest peak in the solar system, Olympus Mons. Many believed that Mars was full of life until the 90s when people discovered that it was a barren dusty planet devoid of any life. Mars has no magnetic feild. It has two moons, Phobos and Diemos. It can get as cold as -195°F at it's poles. Mars has many volcanoes but none apear to be active. Mars is right next to the asteroid belt.

Black Holes

Black Hole Drawing
Black holes are small areas of space that have such strong gravity that nothing, not even light can escape. planets, stars, gas dust, and even energy are devoured by black holes. Some people think that black holes can teleport you to other places. The bitter truth is that they are angry beasts that rip everything apart atom by atom. Black holes are one of the most powerful forces in the universe. They are collapsed supergiant stars. They are only detected when the start swallowing a star because, suddenly, the star is gone.

Venus

The surface of Venus
Venus is the hottest planet in the solar system at 900°F. It has a mostly Carbon Dioxide atmosphere which creates a powerful greenhouse effect. At its closest, Venus is only 41,840,000 km away. Venus is the most active planet in the solar system with many volcanos. It has a molten, hot surface and is almost exactly the same size as earth. Its surface is a rocky, dusty, waterless expanse of mountains, canyons, and plains, with a 200-mile river of hardened lava. This is not the place to be. Venus also takes 243 Earth days just to rotate once!
