Jupiter is the fifth planet
from the Sun. It is the largest planet, over 11 times the
size of Earth. It is so large, you can fit 1,400 Earths
Jupiter is mostly a large ball of gas.
It is made up of hydrogen, helium, methane, water and
ammonia. Jupiter's atmosphere looks like cloud belts and
stripes. The clouds form belts because of Jupiter's fast
rotation. It spins over 2 times faster than Earth.
Speculation is that if Jupiter were larger, it might
have been a sun. Jupiter has atleast 16 moons orbiting
it, much like the planets revolving around the Sun. The
four largest moons are Ganymede, Callisto, Io and Europa.
The moon Ganymede is even larger than the planet Mercury.
