Jupiter is the largest planet in the Solar System and the first of the four Gas Giants. The
planet is the fourth brightest object visible from Earth after the Sun, the Moon and Venus. The planet has a
"red spot"
which is a storm that has been observed on Jupiter since the planet was discovered. Jupiter also has a ring system like
all of the large gas planets, although these rings aren't as famous or as visible as Saturn's. Orbiting Jupiter are also
at least 63 moons, most of which were discovered in the 21st Century! Jupiter's moon Ganymede is the largest in the Solar
System, bigger than Mercury and Pluto!
