The planet known as the "Gas Giant" is Jupiter. As the largest planet in our solar system, Jupiter is primarily composed of hydrogen and helium, lacking a solid surface like terrestrial planets. Its massive size and gravitational pull influence many other celestial bodies, including the asteroid belt and various moons. Jupiter is renowned for its Great Red Spot, a persistent storm larger than Earth, and its stunning banded atmosphere, characterized by colorful cloud stripes. This gas giant plays a pivotal role in our understanding of planetary formation and dynamics, making it a prime target for astronomical study and exploration.
