8.3: Gas Giant Planets
Like the Rocky Planets, the Gas Giant planets – sometimes referred to as the Jovian Planets (Jupiter-like) – also have a number of general characteristics. Gas Giant planets are large in size when compared to the Rocky Planets.
Gas Giant planets are made up of primarily Gases – thus their name – with basically the same compounds and elements, but differing percentages. These worlds are not primarily composed of rock or other solid matter as the Rocky Planets.
Some other Gas Giant characteristics include short revolution periods (when compared to the Rocky Planets), many moons, rings, and farther from the Sun in our solar system thus the longer periods of revolution.
