Solar system

  1. 1. Solar System<br />By: William Meng<br />
  2. 2. Revolve?<br />Revolve means for a smaller object to move around a larger object.<br />Planets revolve around the sun.<br />
  3. 3. Rotation<br />Rotate is similar to spinning. When a planet rotates, its spins itself on its axis.<br />The Earth Rotates<br />
  4. 4. Difference between Inner and Outer Planets<br />Inner planets are inside asteroid belt, Outer planets are outside of asteroid belt.<br />Inner planets are smaller than outer planets<br />Inner planets are mostly made of rock, outer planets are mostly made of gas.<br />
  5. 5. Craters in inner planets?<br />There are more craters in the inner planets because sun’s gravity attracts asteroids from the asteroid belts to the inner planets.<br />
  6. 6. Orbit<br />Orbit is the path a planet/satellite follows when it revolves around a larger object.<br />This Satellite orbits around the sun.<br />
  7. 7. A Planet<br />A planet needs to have:<br />Large enough so the gravity is strong enough to make the planet round<br />Orbits around the sun<br />Cleared out its path<br />
  8. 8. Dwarf Planets<br />Dwarf planets were declared to be the class of objects that have a large enough mass to become round due to gravity and are in orbit around the sun, but have not cleared out its orbital path around the Sun<br />Pluto, Ceres, and Eris are the three dwarf planets.<br />
  9. 9. The 13 planets?<br />
  10. 10. Solar System Picture<br />
  11. 11. Your Journey Around Solar System Begins Here.<br />BLASTOFF!!<br />==1==<br />~2~<br />3<br />
  12. 12. Mercury<br />Mercury is the closest planet to the sun<br />Thin atmosphere due to weak gravity.<br />Helium and sodium are found on its atmosphere.<br />Impact cratering, volcanism, and tectonic activity shaped Mercury.<br />
  13. 13. Venus<br />
  14. 14. Earth<br />
  15. 15. The Moon<br />Moon. Earth’s only satellite and companion<br />
  16. 16. Mars<br />Ancient bacteria and other small signs of life suggest that there was once life on Mars<br />Atmosphere is mainly carbon dioxide<br />Olympus Mons is a large volcano on Mars.<br />Two satellites are Phobos and Deimos.<br />
  17. 17. Asteroid Belt<br />
  18. 18. Jupiter<br />Jupiter rotates very fast. This allows its poles to be flatter and round in the center.<br />Hydrogen, helium, sulfur, and nitrogen make up its atmosphere.<br />The Great Red Spot is a large hurricane on Jupiter.<br />Jupiter has 63 satellites.<br />
  19. 19. Saturn<br />Hydrogen and helium make up Saturn’s atmosphere.<br />Saturn’s rings are believed to be formed by its moons<br />The ring is composed of dust and ice.<br />Saturn could float in water due to its low density.<br />Seasons in Saturn last 7 years.<br />
  20. 20. Uranus<br />Uranus tilts at 98 degrees. It seems like it rotates on one side.<br />Hydrogen, helium, and methane make up its atmosphere.<br />It has 27 known satellites.<br />
  21. 21. Neptune<br />Ammonia, helium, and methane make up its atmosphere.<br />Neptune has 13 known satellites.<br />Triton is Neptune’s largest satellite. Astronomers think that it was captured by Neptune’s gravity and forced it to revolve around Neptune.<br />
  22. 22. Pluto<br />Charon, Nix, and Hydra are Pluto’s three moons.<br />Scientists learned using a spectroscope that there was methane frost on Pluto and water frost on Charon. <br />Charon shares atmosphere with Pluto.<br />
  23. 23. Ceres<br />It takes 4.6 Earth years for Ceres to make one revolution.<br />Ceres was once considered an asteroid because it was in the asteroid belt.<br />Its surface is covered with a mixture of water ice, carbonates, and clays.<br />
  24. 24. Eris<br />Xena was Eris’ original name.<br />It takes 557 Earth years for Eris to make one orbit around the sun.<br />Dysnomiais Eris’s moon<br />It did not clear out its orbit, so it could not be a planet.<br />
