Review: Name the inner planets in order. The Outer Planets General • Most of these Planets are – – – – Mostly Gas Massive Atmospheres Solid Cores due to pressure All have rings • Are called the Gas Giants (but Pluto) – Mostly made up of Hydrogen and Helium • Pluto is more like inner planets then outer planets Jovian Planets -Jupiter is the fifth planet from the sun. -Jupiter is the largest planet in our solar system. Jupiter has 63 known moons. -It has a giant red spot which is a storm. -Jupiter is so big that you could put every planet from our solar system in it if it were hollow. -If you weighed 100 pounds on Earth you would weigh 254 pounds on Jupiter. It is 480,000,000 miles away from the sun. Jupiter -Saturn is the sixth planet from the sun. -It is the second largest planet. -It has dozens of rings that are made of ice and rock and they can be as small as a fingernail and as big as the size of a car. -Saturn is made out of hydrogen and helium. If there was an ocean big enough to hold Saturn it would float. -Saturn has 60 moons. Saturn -Uranus is the seventh planet from the sun. -It is the third largest planet in our solar system. It has 11 rings and 27 known moons. -Uranus is the only planet in our solar system that spins on it’s side. -It is the size of 14 Earths. It is 1,850,000,000 miles from the sun. -It is a frozen planet with a molten core. Uranus -Neptune is the eighth planet from the sun. -Neptune has eight narrow, faint rings in clumps. -Neptune was the first planet whose existence was predicted mathematically. -Neptune is over 16 times the size of Earth. A day on Neptune is 19.1 Earth hours. One year on Neptune is 164.8 Earth years. Neptune is 4,546,000,000 miles from the sun. 13 moons. Neptune -Pluto is now considered a dwarf planet and is no longer counted as a true planet. -Each day on Pluto is 6.39 Earth days. A year on Pluto is 247.7 Earth years. Pluto is very cold. It can be between -396° to 378°F. -Pluto has 3 moons, and the largest, Charon, is almost the size of Pluto. Pluto
