  • 1. Touring Our Solar System Interactive Power Point Project Erin Lewis ED 205-05
  • 2. The Outer Planets The Asteroid Belt Comets The Sun Planet Earth The Inner Planets Our Solar System
  • 3. The Solar System
    • Our solar system is about 4.5 billion years old
    • It has one star, (our Sun) and eight planets
  • 4. The Sun
    • The Sun is one of
    • about 200,000 million
    • stars in our Galaxy!
    • It creates light and
    • heat through nuclear
    • fusion
  • 5. The Inner Planets
    • Mercury
    • Venus
    • Earth
    • Mars
    • The four “Inner” Planets of our solar system are made of mostly rock and metal
    • They are also much smaller in size and mass compared to the “Outer” Planets
  • 6. Mercury
    • Closest Planet to
    • our Sun
    • Smallest Planet in
    • solar system
    • No Moons
  • 7. Venus
    • Second closest planet to Sun
    • Closest in size to Earth
    • Heavy atmosphere of Carbon Dioxide
    • No moons
  • 8. Planet Earth
    • Earth is the only planet in our solar system that has liquid water and a breathable atmosphere
    • Over 70% of Earth is covered by water
    • Earth is the only planet in our solar system that can sustain life
  • 9. Mars
    • Fourth planet from the Sun
    • Often called the “red planet” due to its red (rusty) soil
    • Two moons – Phoebos and Deimos
    • Been visited by three Earth “Rovers”
  • 10. The Asteroid Belt
    • The asteroid belt is located between Mars and Jupiter
    • It consists of rocky bodies that range in size between boulders and small moons
    • It’s believed that this “belt” may once have been a planet that collided with another very large body in space, and broke into millions of pieces
  • 11. The Outer Planets
    • Jupiter
    • Saturn
    • Uranus
    • Neptune
    • * Pluto
    • The Four “Outer” Planets of our solar system are made of gases, such as methane and hydrogen
    • They are much larger in size and mass than the “Inner” Planets
  • 12. Jupiter
    • Largest planet in solar system
    • Fifth planet from the Sun
    • Known for its Giant Red Spot, a huge hurricane type storm in atmosphere
    • Has over 25 moons
  • 13. Saturn
    • Sixth planet from the Sun
    • Known for its massive system of “rings”, made of ice and rock particles
    • Has at least 16 moons
  • 14. Uranus
    • This bluish planet is made of mostly methane gas
    • Like, Saturn, it also has a distinctive ring system
    • It is the only planet that rotates flopped over on its side
  • 15. Neptune
    • This gigantic planet also has a storm raging on its surface, just like Jupiter. It’s called “the great blue spot”.
  • 16. Pluto
    • In 2006, astronomers decided that Pluto, by definition, is no longer a planet.
    • It is considered a “protoplanet”, or dwarf planet, due to its small size and strange orbit.
    • Pluto has one moon; Charon
  • 17. Comets
    • Comets are like “dirty snowballs”. They are made of mostly ice and and rock
    • They usually orbit the Sun at great distances; much further out than even Pluto!
    • Sometimes, a comet is knocked out of this distant orbit. As it approaches the Sun, its ice begins to melt and forms its characteristic tail
  • 18. Author’s Biography
    • My name is Erin Lewis, and I’m a senior at GVSU. My major is Group Social Studies, secondary education, with a minor in Earth/Space science.
    • This slide show represents a virtual tour of our solar system and its eight planets.
