Jupiter is the largest planet in our solar system.  Largely made up of hydrogen and helium, Jupiter has the appearance of being layered. This effect is further enhanced by alternating east and west winds with separate zones of composition and temperature. The “Great Red Spot,” has winds of an estimated 400 miles per hour.

Jupiter’s extremely large number of moons include the four Galilean moons, Io, Europa, Ganymede and Callisto. Discovered by Galileo Galilee over 400 years ago.
