  1. Solar System Can You Name the Planets? NSF North Mississippi GK-8

  2. Major Solar System Bodies • Sun • Mercury • Venus • Earth • Mars • Asteroid Belt • Jupiter • Saturn • Uranus • Neptune • Pluto Terrestrial Jovian NSF North Mississippi GK-8

  3. Mnemonics M V E M J S U N P • My Very Educated Mother Just Served Us Nine Pies • My Very Easy Memory Jingle Seems Useful Naming Planets NSF North Mississippi GK-8

  4. NSF North Mississippi GK-8

  5. Solar System Roughly to Scale NSF North Mississippi GK-8

  6. Sun • A star • Also called “Sol” • 99.86% of Solar System mass • All other objects rotate around the Sun NSF North Mississippi GK-8

  7. Terrestrial Planets • Terrestrial means “Terra-like” • Terra is another name for Earth • Four Terrestrial Planets • Mercury • Venus • Earth • Mars • None have rings, some have moons NSF North Mississippi GK-8

  8. Mercury • Closest to the Sun • Covered in craters • Second smallest • Only planet with scarps • Only partially explored • No atmosphere • 800 °F peak temperature NSF North Mississippi GK-8

  9. Venus • Earth’s “sister planet” • Extremely hot • 96% carbon dioxide atmosphere • 90 atmospheres of pressure • Sulfuric acid rain (battery acid) NSF North Mississippi GK-8

  10. Earth • Only planet with known life • Only planet with a hydrosphere • Visible moon • Also called “Terra” • Densest planet NSF North Mississippi GK-8

  11. Moon • Not a planet • Easily visible • Formed by giant impact • Covered in craters NSF North Mississippi GK-8

  12. Moon Craters NSF North Mississippi GK-8

  13. Moon Landing Buzz Aldrin (posing) Neil Armstrong (reflection) July 20, 1969 NSF North Mississippi GK-8

  14. Aldrin(Posing)Armstrong(reflection) NSF North Mississippi GK-8

  15. Earth Rise NSF North Mississippi GK-8

  16. Mars • The “Red Planet” • Carbon Dioxide polar caps • Two moons (captured asteroids) • NASA currently exploring NSF North Mississippi GK-8

  17. Mars Viking Lander NSF North Mississippi GK-8

  18. Mars Viking Lander NSF North Mississippi GK-8

  19. Mars’s moons Phobos Deimos NSF North Mississippi GK-8

  20. Asteroid Belt • Stretch of Asteroids between Mars and Jupiter • Very sparsely populated • First Asteroid ever discovered was Ceres. Eros Ida NSF North Mississippi GK-8

  21. Jovian Planets • Jovian means “Jove-like” • Jove is another name for Jupiter • Also called “Gas Giants” • Four Jovian Planets • Jupiter • Saturn • Uranus • Neptune • All have moons and rings NSF North Mississippi GK-8

  22. Jupiter • Great Red Spot • Largest planet • 318 times as massive as Earth • At least 63 moons • 4 Galilean moons • Also called Jove NSF North Mississippi GK-8

  23. Great Red Spot • Permanent Hurricane • At least 300 years old • Larger than the Earth • Winds move several hundred mph NSF North Mississippi GK-8

  24. Galilean moons NSF North Mississippi GK-8

  25. Saturn • Easily visible rings • Rings created from former moons • Gas Giant • Second largest • 34 moons • Titan NSF North Mississippi GK-8

  26. Titan • Only moon with full atmosphere • Similar to early Earth • Ice volcanoes spew ammonia (like window cleaner) • Cassini-Huygens probe • Methane or Ethane seas NSF North Mississippi GK-8

  27. Titan Probe Image Panorama NSF North Mississippi GK-8

  28. Uranus • Relatively featureless • Tilted over 90 degrees • Blue-green • Methane atmosphere • 27 moons NSF North Mississippi GK-8

  29. Neptune • Extremely Blue • Same size (roughly) as Uranus • Great dark spot • Atmospheric hole • Strong storms • 13 moons NSF North Mississippi GK-8

  30. Pluto • Smallest planet • Neither Jovian nor Terrestrial • May not be a planet • One moon, Charon • No rings • Not explored • Highly elliptical orbit • 20 of every 248 years, Neptune is further NSF North Mississippi GK-8

  31. Pluto and Charon NSF North Mississippi GK-8

  32. Review • How many planets are there? • There are 9 planets. • Can you name the planets in order from the Sun? • Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. NSF North Mississippi GK-8

  33. Review • What is the smallest planet? • Pluto • What is the largest planet? • Jupiter • Which planet is closest to the Sun? • Mercury NSF North Mississippi GK-8

  34. Review • Which planet is furthest from the Sun? • Pluto • Which planet is called “The Red Planet”? • Mars • Which planet has sulfuric acid rain and is called Earth’s “sister”? • Venus NSF North Mississippi GK-8

  35. Review • Which planet is known for its rings? • Saturn • Can you name some Solar System objects which are not planets? • The Sun, The Moon, other moons, Asteroids NSF North Mississippi GK-8
