Gas giants are a type of planet in our solar system or in other solar systems that are primarily composed of gaseous materials, such as hydrogen and helium. These planets are typically much larger in size and mass than terrestrial planets like Earth, and they lack a solid surface. Gas giants are characterized by thick atmospheres that can contain complex weather patterns, including high-speed winds, massive storms, and unique cloud formations. Some gas giants, like Jupiter and Saturn in our solar system, have multiple moons and intricate ring systems. Scientists study gas giants to better understand the formation and evolution of planetary systems, as well as the physics of gas dynamics and atmospheres. Observations of gas giants can also provide insights into the composition and conditions of other planets in our galaxy.
