Gas Giants

Gas giants are large planets that primarily consist of gases, such as hydrogen and helium, rather than a solid surface. They have thick atmospheres and can be characterized by their significant mass, which allows them to retain these lighter elements. Gas giants typically have complex weather systems, including strong winds and storms, and may possess rings and numerous moons. The four main gas giants in our solar system are Jupiter and Saturn, which are classified as “true” gas giants, and Uranus and Neptune, which are often referred to as “ice giants” due to their higher concentrations of substances like water, ammonia, and methane. Gas giants can be contrasted with terrestrial or rocky planets, which are composed mainly of solid materials and have defined surfaces. The study of gas giants helps astronomers understand planetary formation and the dynamics of the solar system, as well as exoplanetary systems beyond our own.
