Jupiter is the fifth planet in the solar
system and is the largest
A day on Jupiter is less than 10 hours
but it takes Jupiter 12 Earth years to
orbit the sun once

Jupiter is surrounded by thick clouds of
gas
Most scientists believe that liquid lies
under the clouds

Saturn is the sixth planet from the sun
It is the second largest planet in the
solar system

that make it very colorful
It takes almost 30 Earth years for
Saturn to make one orbit around the
sun

Saturn has at least 58 moons
8
Uranus is the seventh planet from the
sun
Uranus also has rings surrounding it
9
The rings are formed by an unknown black
material which may be black carbon
coating the rings of methane gas
It takes Uranus 84 years to orbit once
around the sun
10
Scientists discovered Neptune and
Pluto by using mathematics
Although scientists are no longer
calling Pluto a planet, we will still
include it
11
Neptune is the eighth planet from the
sun
It takes Neptune about 165 years to
orbit the sun one time
12
Neptune is covered with a thick layer
of icy clouds
The interior of Neptune may be a
central rocky core

Pluto is the farthest planet from the
sun and the one we know the least
