The Outer Planets
By: Mr. Leslie’s Class
Inner Planets
• Mercury – (closest to the sun) has many large and small
craters. These craters are very old. There are plains
between the craters
• Venus – has highlands and rolling hills as Earth’s land
areas do. Venus also has lowlands much like Earth’s
ocean floors
• Earth – You live here!!!
• Mars – Mars has a dusty surface and many volcanoes.
Mars is the planet most like Earth.

Outer Planets
• The four planets farthest from the Sun are
called the outer planets.
• Jupiter, Saturn, Uranus and Neptune are
often called the GAS GIANTS.
• They are the largest planets in the solar
system and are made up mostly of gases.
Jupiter
• Jupiter is the largest planet. More than a 1,000
Earths would fit inside it!
What is it made of:
Average Temperature:
How much would a 65 pound
person weight:
Distance from sun (compared to
Earth)
Interesting Fact:

Four of Jupiter’s moons can be
seen through binoculars.
Saturn
• Saturn’s rings are made of pieces of ice, dust,
and rocks. (some pieces are as large as houses)
What is it made of:
Average Temperature:
Hydrogen and helium
-220°F
How much would a 65 pound
person weight:
About 69 pounds
Distance from sun (compared to
Earth)
10 times as far
Interesting Fact:
Saturn is so light that it could float
in water.
Uranus
• Uranus was discovered in 1781 by William
Herschel. Its rings were not discovered until
1977. Uranus appears to rotate on its side.
What is it made of:
Average Temperature:
How much would a 65 pound
person weight:
Distance from sun (compared to
Earth)
Interesting Fact:
Hydrogen, helium and methane
-323°F
About 59 pounds
19 times as far
Unlike other planets, Uranus
appears to rotate on its side.
Neptune
• Neptune has a very active atmosphere. Winds
can blow at 1,450 kilometers an hour. Neptune
has huge storms. Some of these storms are as
big as Earth.
What is it made of:
Average Temperature:
How much would a 65 pound
person weight:
Distance from sun (compared to
Earth)
Interesting Fact:
hydrogen, helium, and methane
-328°F
About 73 pounds
30 times as far
Neptune has a magnetic field that
is 25 times stronger than that of
Earth.
Pluto, a dwarf planet
• Pluto was once known as the ninth planet. Every
248 years, Pluto’s orbit moves inside of
Neptune’s orbit making it closer to the Sun.
What is it made of:
Average Temperature:
How much would a 65 pound
person weight:
Distance from sun (compared to
Earth)
Interesting Fact:
Nitrogen and methane

Pluto is smaller than some of the
moons in the solar system.
