3. Jupiter Volume of Jupiter could fit 1,000 Earth’s inside
5.20 AU from the Sun
Atmosphere made of 80% hydrogen & 20% helium
Period of Revolution: 11.9 years or approx. 12 years
Number of 63 Moons
The moons of Jupiter were caused by collisions between Jupiter’s moons and meteorites

4. Saturn Saturn’s diameter is nearly 9.4 times bigger than Earth’s
9.6 AU from the Sun or nearly 10 AU
Period of revolution: 30 years
Saturn has rings that are made of pieces of ice that resemble broken glass because they vary in size from small pieces to very large
Saturn is a gas giant because it has an atmosphere made of hydrogen and helium
This planet has at least 60 moons

5. Uranus
This planet although it is the 7th planet from the Sun, the diameter of the planet is only 4 times bigger than the diameter of Earth
Atmosphere made of hydrogen and helium
Traces of methane exist on this planet that give the planet its blue tint
Period of revolution is approximately 165 years
30.1 AU from the Sun
Has 13 moons

6. Neptune Discovered in 1846 (later in comparison to others)
Atmosphere of hydrogen and helium
Traces of methane give it a blue tint like Uranus
13 moons
Period of Revolution: 165 years
Largest moon is named Triton, made up of rock with an icy outer layer. Made up of frozen nitrogen gas

8. Photo of Uranus
Uranus is the only giant planet whose equator is nearly at right angles to its orbit. A collision with an Earth-sized object may explain Uranus' unique tilt. Nearly a twin in size to Neptune, Uranus has more methane in its mainly hydrogen and helium atmosphere than Jupiter or Saturn. Methane gives Uranus its blue tint.

Dark, cold and whipped by supersonic winds, Neptune is the last of the hydrogen and helium gas giants in our solar system. More than 30 times as far from the sun as Earth, the planet takes almost 165 Earth years to orbit our sun. In 2011 Neptune completed its first orbit since its discovery in 1846.
