True gas giants are composed mostly of hydrogen and helium, similar to the sun. These worlds are composed primarily of silicate rocks and metals, with a distinct separation into a metallic core, a rocky mantle, and a thin crust.
2 Types of Planets: Terrestrial and Gas Giants
Earth: The only known planet to support life, with a dynamic surface of oceans and continents. This simple difference in formation environment dictates whether a world becomes a dense, compact terrestrial planet or a sprawling, gaseous giant.
Terrestrial Planets: The Solid Worlds Terrestrial planets, named after Terra, the Latin word for Earth, are defined by their solid, rocky surfaces and relatively high densities. Understanding these distant bodies begins with classifying the 2 types of planets that dominate our cosmic neighborhood: the rocky terrestrial worlds and the vast gas giants.

These "ices" dominate the planet's mass, even though they are hot and pressurized into exotic states far removed from the water ice we know on Earth. Uranus: An ice giant that rotates on its side, likely due to a colossal ancient impact.
