The planet known for its big storm called the Great Red Spot is Jupiter. The Great Red Spot is a gigantic storm, larger than Earth, that has been raging for centuries. It is characterized by its reddish color and high-pressure system, with winds that can reach speeds of up to 400 miles per hour (640 kilometers per hour). This storm is a fascinating feature of Jupiter’s atmosphere, which is primarily composed of hydrogen and helium, and represents one of the most prominent and studied phenomena in the solar system, illustrating the planet's dynamic weather.
