Document Summary
In this chapter, we saw that the jovian planets really are a different kind of planet and, indeed, a different kind of planetary system. As you continue your study of the solar system, keep in mind the following big picture ideas: the jovian planets dwarf the terrestrial planets. Each new set of circumstances we discover offers new opportunities to learn how out universe works. What are jovian planets made of: jupiter and saturn are made almost entirely of hydrogen and helium, while uranus and neptune are made mostly of hydrogen compounds mixed with metal and rock. They lack solid surfaces but have very high internal pressures and densities. Each jovian planet has a core about 10 times as massive as. Earth, consisting of hydrogen compounds, metals, and rock, so they differ mainly in their surrounding layers of hydrogen and helium.
