The Outer Planets Gas Giants

• The four planets farthest away from the Sun are
  called the outer planets.
• These planets are
• Jupiter Saturn Uranus Neptune

6
Why Gas Giants

• These Planets do not have a hard rocky surface
  like Earth does.
• They all are much bigger than Earth.

7
Why are they so big?

• They are made of mostly Hydrogen and
  helium(balloon) gases, and a few other gases.
• They are so far from the Sun that the gases are
  very cold and liquid.
• They are not heavy and solid like rocks.

8
Jupiter

• It is our biggest planet, over 1000 times bigger
  than Earth.
• It is 400 times farther from the Sun than earth
  and so cold that its hydrogen and helium gases
  turn to liquid.
• Jupiters moon Europa is covered with ice and
  maybe life forms.

9
Saturn

• It is the second largest planet and has the
  largest and most visable rings.
• Like Jupiter,it is made up of liquid hydrogen and
  helium liquid gases.
• Its rings are made from ice and rock from an
  exploding Moon.

10
Uranus

• It is twice as far from the Sun as Saturn and
  only 4 times bigger than earth.
• It spins on its side because its axis is
  horizontal.
• Its blue-green color comes from the frozen
  methane gases trapped in the helium/hydrogen
  gases.

11
Neptune

• The smallest and farthest gas planet from the
  sun.
• It also appears blue because of the frozen liquid
  methane gas on its surface.

12
Pluto

• Has a solid surface and is much smaller and
  denser than the other outer planets
• Has at least one moon Charon which is large and
  considered a double planet

13
Is Pluto A Planet?

• It is very small
• There are other things in space that are larger
  than Pluto.
• It is highly published as a planet
• At one time was removed from the text as a planet
• It is a body worthy of study (video)
