Solar system

  1. 1. Earth Science An overview of the Solar System
  2. 2. The Sun <ul><li>The sun is the biggest, brightest, and hottest object in the solar system. </li></ul><ul><li>The sun is an ordinary star. </li></ul><ul><li>The sun is made of about 70% hydrogen and 28% helium. </li></ul>
  3. 3. Mercury <ul><li>Mercury is solid and is covered with craters. </li></ul><ul><li>Mercury has almost no atmosphere. </li></ul><ul><li>Mercury is the eighth largest planet. </li></ul>
  4. 4. Venus <ul><li>Venus is the sixth largest planet. It’s about three-fourths the size of earth. </li></ul><ul><li>The surface is rocky and very hot. The atmosphere completely hides the surface and traps the heat. </li></ul>
  5. 5. Earth <ul><li>Earth is the fifth largest planet and the third from the sun. </li></ul><ul><li>Liquid covers 71 percent of the Earth’s surface. </li></ul><ul><li>The Earth has one moon. </li></ul>
  6. 6. Moon
  7. 7. Mars <ul><li>Mars is the fourth planet from the sun. </li></ul><ul><li>Mars has a thin atmosphere that contains mostly carbon dioxide. </li></ul><ul><li>Mars has two small moons. </li></ul>
  8. 8. Moons of Mars <ul><li>Phobos </li></ul><ul><li>Deimos </li></ul>
  9. 9. Jupiter
  10. 10. Jupiter’s Red Spot <ul><li>The Great Red Spot, a huge storm of swirling gas that has lasted for hundreds of years. </li></ul><ul><li>Jupiter does not have a solid surface. The planet is a ball of liquid surrounded by gas. </li></ul>
  11. 11. Moons of Jupiter <ul><li>Jupiter has four large Galilean moons, twelve smaller named moons and twenty-three more recently discovered but not named moons. </li></ul><ul><li>We’ll take a look at the four large Galilean moons which were first observed by Galileo in 1610. </li></ul>
  12. 12. Io <ul><ul><li>Io is the fifth moon of Jupiter. It’s the third largest of Jupiter’s moons. </li></ul></ul><ul><ul><li>Io has hundreds of volcanic calderas. Some of the volcanoes are active. </li></ul></ul>
  13. 13. Europa <ul><li>Europa is the sixth of Jupiter’s moons and is the fourth largest. </li></ul><ul><li>It is slightly smaller than the Earth’s moon. </li></ul><ul><li>The surface strongly resembles images of sea ice on Earth. There may be a liquid water sea under the crust. </li></ul><ul><li>Europa is one of the five known moons in the solar system to have an atmosphere. </li></ul>
  14. 14. Ganymede <ul><li>Ganymede is the seventh and largest of Jupiter’s known satellites. </li></ul><ul><li>Ganymede has extensive cratering and an icy crust. </li></ul>
  15. 15. Callisto <ul><li>Callisto is the eighth of Jupiter’s known satellites and the second largest. </li></ul><ul><li>Callisto has the oldest, most cratered surface of any body yet observed in the solar system. </li></ul>
  16. 16. Saturn <ul><li>Saturn is the second largest planet and the sixth from the sun. </li></ul><ul><li>Saturn is made of materials that are lighter than water. If you could fit Saturn in a lake, it would float! </li></ul>
  17. 17. Rings of Saturn <ul><li>Saturn’s rings are not solid; they are composed of small countless particles. </li></ul><ul><li>The rings are very thin. Though they’re 250,000km or more in diameter, they’re less than one kilometer thick. </li></ul>
  18. 18. Uranus <ul><li>Uranus is the third largest planet and the seventh from the sun. </li></ul><ul><li>Uranus is one of the giant gas planets. </li></ul><ul><li>Uranus is blue-green because of the methane in its atmosphere. </li></ul>
  19. 19. Neptune <ul><li>Neptune is the fourth largest planet and the eight from the sun. </li></ul><ul><li>Because of the orbits, from 1979 to 1999, Neptune was the ninth planet. </li></ul><ul><li>Like Uranus, the methane gives Neptune its color. </li></ul>
  20. 20. Pluto <ul><li>Pluto is the smallest planet and usually the farthest from the sun. </li></ul><ul><li>Pluto is the only planet that has not been visited by a spacecraft. </li></ul>
