3Jupiter Volume of Jupiter could fit 1,000 Earth’s inside 5.20 AU from the SunAtmosphere made of 80% hydrogen & 20% heliumPeriod of Revolution: 11.9 years or approx. 12 yearsNumber of 63 MoonsThe moons of Jupiter were caused by collisions between Jupiter’s moons and meteorites
4Saturn Saturn’s diameter is nearly 9.4 times bigger than Earth’s 9.6 AU from the Sun or nearly 10 AUPeriod of revolution: 30 yearsSaturn has rings that are made of pieces of ice that resemble broken glass because they vary in size from small pieces to very largeSaturn is a gas giant because it has an atmosphere made of hydrogen and heliumThis planet has at least 60 moons
5UranusThis planet although it is the 7th planet from the Sun, the diameter of the planet is only 4 times bigger than the diameter of EarthAtmosphere made of hydrogen and heliumTraces of methane exist on this planet that give the planet its blue tintPeriod of revolution is approximately 165 years30.1 AU from the SunHas 13 moons
6Neptune Discovered in 1846 (later in comparison to others) Atmosphere of hydrogen and heliumTraces of methane give it a blue tint like Uranus13 moonsPeriod of Revolution: 165 yearsLargest moon is named Triton, made up of rock with an icy outer layer. Made up of frozen nitrogen gas

8Photo of UranusUranus 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.
9Photo of Neptune http://solarsystem. nasa. gov/planets/profile. cfm 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.
