2
THE SUN

• Nine planets orbit the sun
• The closest star to Earth, and because of its
  close distance it is bright enough to sustain
  life on Earth
• The Sun is the center of our Solar System
• The Suns surface is 15,000,000 degrees Celsius
• The Suns gravity keeps all of the planets in
  orbit, instead of flying off into space
• Its diameter is 1.4 million KM, 110 times the
  diameter of the Earth

3
Mercury
Closest planet to the Sun Undertakes extreme
temperatures Is spotted with craters Mercury is
.4 AU from the sun Has no atmosphere Temperatures-
670K-103K A day on Mercury is 176 Earth days No
life on Mercury, due to no atmosphere
4
Venus

• 2nd planet from the sun
• .7 AU from the sun
• Thick layers of carbon dioxide clouds rest on
  Venus which make Venus very reflective
• Venus has mountains and plains
• Unlike other planets, Venus rotates in the
  opposite direction (east to west)
• Venuss environment cannot support life because
  the atmosphere is thickly laced with sulfuric
  acid
• Venus has a very strong greenhouse effect

5
Earth

• Third planet from the sun
• Only planet that has proven to sustain life so
  far
• Has one moon
• 80 percent water
• Ideal conditions for life
• Earths atmosphere protects us from radiation
  from space

6
Mars

• Fourth planet from the sun
• Many missions have been sent to Mars
• Has the largest volcanoes in the Solar System
• Believed that water used to run on Mars
• Temp- 144K to 300K

7
Jupiter

• Gas Giant
• Fifth planet from the sun
• Great Red spot is a giant storm 3 times the size
  of Earth
• 61 moons
• 1 day on jupiter is 10 hrs, 1 year is 12 Earth
  years

8
Saturn

• Gas giant
• Biggest ring system
• 1 day is 10.7 Earth hours
• Rings are made of dust, ice, and rock particles
• Saturn may still be forming
• Saturns outer layers are made of helium

9
Uranus

• Gas Giant
• Gaseous atmosphere consists of hydrogen, helium,
  and methane
• Methane colors Uranus blue
• 7th planet from the sun
• 84 y to orbit the sun
• 30 AU from the sun

10
Neptune

• 8th planet from the sun
• 1 day is 16 hrs
• Very close atmosphere to Uranus
• 1 year on Uranus is 164 Earth years

11
Pluto

• The oddball planet
• 1 y is 284 earth y
• Discovered 1930
• Solid icy surface, thin gaseous atmosphere
• Orbits sun on long ellipse, on a different angle
  than the rest
• 40 AU from the sun

12
The Asteroid and Kuiper Belt

• Between Mars and Jupiter
• Divides the inner/outer planets
• Asteroids are 3km to 700km in diameter
• Made of iron, nickel, water, rock
• The Kuiper Belt lies on the outside of the Solar
  System
• Made of pieces of planets from the formation of
  the Solar System
• Lies beyond the orbit of Neptune
