The planet known for the "Great Red Spot" is Jupiter. This prominent feature is a massive, persistent storm that has been observed for over 350 years. It is characterized by its reddish color and oval shape, making it easily identifiable in photographs of the planet. The Great Red Spot is about 1.3 times the diameter of Earth, showcasing Jupiter's immense scale. The storm's winds can reach speeds of approximately 432 km/h (268 mph). Researchers believe the Great Red Spot might be changing in size and color, making it an intriguing subject for astronomers and planetary scientists studying Jovian atmospheres.
