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

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

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

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

Photo of Uranus http://solarsystem.nasa.gov/planets/profile.cfm?Object=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.

Photo 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.
