1. Chapter 11 Section 3
Gas Giants

2. The outer planets Also called the Gas Giants
Consist of Jupiter, Saturn, Uranus, and Neptune
Primarily made of hydrogen and helium
Large masses- so strong gravitational pull
Small, solid inner core surrounded by liquid

3. Jupiter Largest planet 1000 Earths would fit in Jupiter
90 % Hydrogen, 10 % Helium- atmosphere
Great Red Spot is a storm of Swirling gases
Core is probably made of rock and metal
Jupiter has at least 63 moons
4 largest are known as Galilean- because they were discovered by Galilei

4. Saturn 90 % hydrogen, 10 % helium Least dense planet
Outer gas layer, liquid layer, small solid core
Ring system is the largest- 7 bands containing thousands of ringlets
Saturn has at lest 60 moons
Titan is a the same size as Mercury

5. Uranus Has narrow dark rings Diameter 4 times Earth
Atmosphere contains hydrogen, helium, and methane
May have a solid rocky core
Uranus has a tilted axis of rotation
Uranus has at least 27 moons
Pretty blue/blue green color due to methane

6. Neptune Atmosphere is made of hydrogen, helium, and methane
Has an iron core surrounded by partially frozen water
Neptune has 13 moons and a faint ring system
Also has a pretty blue/blue green color due to the methane
