5. Solar System Roughly to Scale

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

7. NSF North Mississippi GK-8 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

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

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

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

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

21. NSF North Mississippi GK-8 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

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

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

24. NSF North Mississippi GK-8 Galilean moons

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

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

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

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

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

30. NSF North Mississippi GK-8 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

31. NSF North Mississippi GK-8 Pluto and Charon

32. NSF North Mississippi GK-8 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.

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

34. NSF North Mississippi GK-8 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
