The Solar System


 • Our solar system is located in the
   Milky Way Galaxy.

 • It is made up of planets, moons,
   asteroids, meteoroids and comets.

 Sunspots
                •The sun is a star.
                •It is the largest object in our solar
                system.
Solar eclipse   •The sun is 4.5 billion years old.
                •It‟s surface temperature is 27
                million degrees.
Mercury
                     Mercury
Cratered surface
                   • It is the closest planet to the
                     sun, but not the hottest.
                   • It‟s surface is heavily
                     cratered from meteoroids

visited Mercury
                   • The surface temperature on
                     the dark side of Mercury is
                     –300 degrees F.
Venus
                              Venus
                        • Named for the goddess of love

                        • Earth‟s sister planet- similar
                          in size, mass, density, and
                          volume.
                        • There are 243 Earth days to 1
                          Venus day.
                        • The surface temperature is
                          900 degrees F. , making it the

Earth
                      Earth
Horn of Africa
                 • Earth is 4.5 billion years old.
                 • Seventy percent of the Earth is
                   covered in water.
North America    • The Earth‟s atmosphere keeps
                   the temperatures steady.
                 • As far as we know, it is the
                   only planet with life.

                • Known as “The Red Planet”.
                • Average surface temperature
                  is –67 degrees F.

Jupiter‟s ring
                 • The Great Red Spot is a

 Seeing Our
Solar System
  • Asteroids- very small worlds that
    circle the sun mainly in an asteroid
    belt between Mars and Jupiter

  • Comets- a frozen ball of ice a few
    miles wide, covered by a layer of
    black dust
 Seeing Our
Solar System
  • Meteoroids- small pieces of
    metal or rock from asteroids or
    comets

    have entered the Earth‟s
    atmosphere
