Planet Jupiter

Jupiter, the largest planet in our solar system, is a gas giant composed chiefly of hydrogen and helium. It has a distinct banded appearance with swirling storms. Most notably, the Great Red Spot is a massive storm system. Jupiter is approximately 11 times the diameter of Earth. It has 79 known moons and faint rings, which are difficult to see.

The Great Red Spot

The Great Red Spot is a powerful anticyclone, swirling counterclockwise around the center with wind speeds of 430 to 680 kilometers per hour (270 to 425 miles per hour). And because of its shape and structure, the Great Red Spot is sometimes described as a “pancake.”
