General Description: Jupiter is the largest of the planets. It is
also the largest of the gas giants. It is composed of mainly Hydrogen
and helium. This is the reason that even though it is 1300 times
larger than the earth, it only weighs 318 times as much.  It is known
for its "Red Spot", a giantic storm that has lasted hundreds of years.
Jupiter also has a enormous magnetic field that extends to the orbit
of Saturn. Also a thin ring was discoverd by Voyager.
