Jupiter is the fifth and largest planet in our
solar system. This gas giant has a thick
atmosphere, 39 known moons, and a dark,
barely-visible ring. Its most prominent features
are bands across its latitudes and a great
red spot (which is a storm).
Jupiter is composed mostly of gas.
This enormous planet radiates twice as much
heat as it absorbs from the Sun. It also has an
extremely strong magnetic field. It is slightly
flattened at its poles and it bulges out a bit
at the equator.
