Jupiter

Jupiter the 5th planet from the Sun.

Characteristics
Jupiter has a magnetic field that extends to the orbit of Saturn. Winds on Jupiter are common and reach 300 miles per hour.

Great Red Spot
The Great Red Spot is a large hurricane in Jupiter's atmosphere. Discovered in 1665, the Great Red Spot was roughly 3 times the size of Earth, but it has currently shrunk to slightly larger than Earth. Jupiter's Great Red Spot is shrinking. Although the Great Red Spot is larger than Earth, it's not the largest storm. The largest storms in the Solar System come from Saturn, which has a hexagonal hurricane formed from wind cyclones at it's north pole.

Atmosphere
The Jovian atmosphere is primarily hydrogen and helium, with traces of other gases. Due to Jupiter's gravity, the atmosphere can be highly pressurized.
