The planet with the Great Red Spot is Jupiter. The Great Red Spot is a massive storm located in Jupiter's atmosphere, measuring about 1.3 times the diameter of Earth. It has been continuously observed for over 350 years, indicating its longevity as a storm. The Great Red Spot is characterized by its reddish hue and swirling winds, which can reach speeds of over 400 kilometers per hour (approximately 250 miles per hour). As a gas giant, Jupiter's atmosphere is dynamic and complex, and this enormous storm is one of its most notable features.
