• About Jupiter

  Jupiter is the fifth planet from the Sun, and is the largest planet in the Solar System. Jupiter is almost entirely made of gas, which separates into latitudinal bands. The different bands interact violently, and cause atmospheric storms that are visible from space. The largest of these storms is called the Great Red Spot, and has been observed on the planet for centuries.NinePlanets.org: Jupiter
