Gaseous planets, also known as gas giants, are large celestial bodies primarily composed of hydrogen and helium. Unlike terrestrial planets, they lack a solid surface and have thick atmospheres. The four main gaseous planets in our solar system are Jupiter, Saturn, Uranus, and Neptune. These planets are known for their massive sizes and strong gravitational fields. Gaseous planets often have complex weather systems, including storms and high-speed winds. They also possess ring systems and numerous moons. The study of gaseous planets helps scientists understand planetary formation and the dynamics of atmospheres in different environments across the universe.
