Jupiter is actually the fastest spinning planet
in our solar system! It rotates all the way
around in just about 10 hours, so it has the
shortest day, too! The planet is made up of mostly
gases, unlike Earth. Those gases are hydrogen and
helium, the first two elements in the periodic
table. Since the planet spins so fast, all of
the gas in the middle bulges out a little bit,
making it look like a crushed sphere rather than a
perfect one. Since it's not a perfect sphere,
the rotation times are different depending where
you are on the planet. The equator rotates
faster than the poles do, by about 5 minutes.
The rotation of Jupiter is the fastest in our
Solar system, it only takes about 10 hours,
that means if we experience one day and night
here, you will experience more than twice there in
Jupiter. One more thing, since Jupiter is a gas
planet, it does not rotate as a solid sphere as
our Earth. The rotation near the equator in
Jupiter is a little bit faster than at its poles.
