  2. 2. The Outer Planets The Asteroid Belt Comets The Sun Planet Earth The Inner Planets Our Solar System
  3. 3. The Solar System <ul><li>Our solar system is about 4.5 billion years old </li></ul><ul><li>It has one star, (our Sun) and eight planets </li></ul>
  4. 4. The Sun <ul><li>The Sun is one of </li></ul><ul><li>about 200,000 million </li></ul><ul><li>stars in our Galaxy! </li></ul><ul><li>It creates light and </li></ul><ul><li>heat through nuclear </li></ul><ul><li>fusion </li></ul>
  5. 5. The Inner Planets <ul><li>Mercury </li></ul><ul><li>Venus </li></ul><ul><li>Earth </li></ul><ul><li>Mars </li></ul><ul><li>The four “Inner” Planets of our solar system are made of mostly rock and metal </li></ul><ul><li>They are also much smaller in size and mass compared to the “Outer” Planets </li></ul>
  6. 6. Mercury <ul><li>Closest Planet to </li></ul><ul><li>our Sun </li></ul><ul><li>Smallest Planet in </li></ul><ul><li>solar system </li></ul><ul><li>No Moons </li></ul>
  7. 7. Venus <ul><li>Second closest planet to Sun </li></ul><ul><li>Closest in size to Earth </li></ul><ul><li>Heavy atmosphere of Carbon Dioxide </li></ul><ul><li>No moons </li></ul>
  8. 8. Planet Earth <ul><li>Earth is the only planet in our solar system that has liquid water and a breathable atmosphere </li></ul><ul><li>Over 70% of Earth is covered by water </li></ul><ul><li>Earth is the only planet in our solar system that can sustain life </li></ul>
  9. 9. Mars <ul><li>Fourth planet from the Sun </li></ul><ul><li>Often called the “red planet” due to its red (rusty) soil </li></ul><ul><li>Two moons – Phoebos and Deimos </li></ul><ul><li>Been visited by three Earth “Rovers” </li></ul>
  10. 10. The Asteroid Belt <ul><li>The asteroid belt is located between Mars and Jupiter </li></ul><ul><li>It consists of rocky bodies that range in size between boulders and small moons </li></ul><ul><li>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 </li></ul>
  11. 11. The Outer Planets <ul><li>Jupiter </li></ul><ul><li>Saturn </li></ul><ul><li>Uranus </li></ul><ul><li>Neptune </li></ul><ul><li>* Pluto </li></ul><ul><li>The Four “Outer” Planets of our solar system are made of gases, such as methane and hydrogen </li></ul><ul><li>They are much larger in size and mass than the “Inner” Planets </li></ul>
  12. 12. Jupiter <ul><li>Largest planet in solar system </li></ul><ul><li>Fifth planet from the Sun </li></ul><ul><li>Known for its Giant Red Spot, a huge hurricane type storm in atmosphere </li></ul><ul><li>Has over 25 moons </li></ul>
  13. 13. Saturn <ul><li>Sixth planet from the Sun </li></ul><ul><li>Known for its massive system of “rings”, made of ice and rock particles </li></ul><ul><li>Has at least 16 moons </li></ul>
  14. 14. Uranus <ul><li>This bluish planet is made of mostly methane gas </li></ul><ul><li>Like, Saturn, it also has a distinctive ring system </li></ul><ul><li>It is the only planet that rotates flopped over on its side </li></ul>
  15. 15. Neptune <ul><li>This gigantic planet also has a storm raging on its surface, just like Jupiter. It’s called “the great blue spot”. </li></ul>
  16. 16. Pluto <ul><li>In 2006, astronomers decided that Pluto, by definition, is no longer a planet. </li></ul><ul><li>It is considered a “protoplanet”, or dwarf planet, due to its small size and strange orbit. </li></ul><ul><li>Pluto has one moon; Charon </li></ul>
  17. 17. Comets <ul><li>Comets are like “dirty snowballs”. They are made of mostly ice and and rock </li></ul><ul><li>They usually orbit the Sun at great distances; much further out than even Pluto! </li></ul><ul><li>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 </li></ul>
  18. 18. Author’s Biography <ul><li>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. </li></ul><ul><li>This slide show represents a virtual tour of our solar system and its eight planets. </li></ul><ul><li>For more information, please contact Erin Lewis by email at [email_address] . </li></ul>
