3. Jupiter

4. Jupiters Facts • Mythology – Roman god Jupiter • 5th planet from the sun • Largest planet in our solar system • Gas Giant • Oblate Spheriod shape – Bulge in the middle! • Has at least 63 moons!

5. Jupiters Facts • Mythology – Roman god Jupiter • 5th planet from the sun • Largest planet in our solar system • Gas Giant • Oblate Spheriod shape – Bulge in the middle! • Has at least 63 moons!

6. Jupiter’s Statistics • Orbital Period – 4331. 5 days • Size = 121 Earths • Gravity – 24 m/s • Surface Temp – 165 K (more than 200 C below 0)

7. Jupiter’s Atmosphere • Atmospheric Data comes from Galileo Probe that crashed into the atmosphere of Jupiter • Atmosphere divided into distinct bands

8. Atmosphere

9. Layers of Jupiter • Draw and Label the diagram of Jupiter on your notes • Mostly Hydrogen (88 percent) and helium (12 %)

10. Magnetosphere 14 times as strong as earths

11. Aurora • Three bright dots are magnetic flux tubes that connect to Ion, Ganymede and Europa

12. Aurora

13. Jupiter’s Red Spot • Longest Lasting Storm in history (Discovered in the 1600) • Rotates counterclockwise every 6 days • Slowly fading

14. Jupiter’s Red Eye

15. Jupiters ring System

16. Jupiter’s ring system • Jupiters rings are very difficult to see. • Jupiter's rings were first found by the Voyager 1 spacecraft in 1979 • Three main sections comprise Jupiter's ring system. • Halo ring -The innermost, cloud-like • Main Ring -is quite narrow and thin. • Gossamer Ring-wispy, nearly transparent

18. Jupiter’s Shepherd Moons • Metis • Thebe • Adrastea • Amalthea • INNER • MOONS!

19. Jupiters 4 galilean Satellites • Io • Europa • Callisto • Ganymede

20. BASIC FACTS = discovered by Galileo in 1610 He spotted the four large moons and realized that they were orbiting Jupiter, Not EARTH!!!

21. Io Images of Io Image

22. Io • http://www.youtube.com/watch?v=KXeIll6YYQs • Has a large iron Core (may be molten) • SO2 Atmosphere (Thin) • Closest to jupiter • 4th largest moon • Most volcanically active body in the solar sustem • 400 active volcanoes • blue./white spots are volcanoes erupting

23. Europa Water? Life? • http://www.youtube.com/watch?v=xEtf5lh3SEw • Europa is an Icy satellite • Below Europa’s frozen exterior of ice, there is liquid water • Vast sea could hold microorganisms • Heat generated by planet flexing, keeps water liquid

24. Europa

25. europa

26. Ganymede • Largest Moon in the solar system • Has a magnetosphere • http://www.youtube.com/watch?v=64oBWEsMq2Y • Sounds • http://www.youtube.com/watch?v=6PPEwGJy6PI

27. Callisto • 2nd largest moon of jupiter • Tidally locked • Thin CO2Atmospere • Subsurface ocean • Could be a “human” base for research

28. Saturn

29. Saturn’s Facts • Mythology – names after roman god Saturnus (Saturday!). • 6th planet from the sun • 2nd largest planet in the solar system • Gas Giant • Oblate Spheriod • Less dense then water!

30. Saturn’s Statistics • Orbital Period – 10759 days (29.5 years) • Size = • Gravity= • Surface Temp –

31. Saturn’s Atmosphere

32. Atmosphere • 93.2 % molecular hydrogen, 6.7 %helium • Faint atmosphere bands (lighter than jupiter) • Cloud patterns observed by voyager (hexagonal)

33. Saturn’s Great White spot Giant storm hat happens every 30 years (once a saturian year) Will be another one in 2020

34. Surface • Has a planetary magnetic field, strength in between earth and jupiter • Wind speeds of 1800 km/h

35. Layers of Saturn • Draw and Label the diagram of on your notes • Small core of rock and ice surrounded by a thick layer of metallic hydrogen and a gaseous outer layer

36. Saturn’s ring System

37. Saturns’s ring system • First discovered by Galileo in 1610 • Rings consist mostly of ice with small amounts of debris and dust • Theories: • Roche - Rings were once a moon of saturn that was ripped apart by tidal forces • Secondary – Rings are left over from original nebular material from which saturn formed

38. Saturns’s ring system - FEATURES • Features: • Cassini division • Enckle Gap • Possess own atmosphere of molecular O2 different from saturn

39. Roche Limit

40. Moons • 61 moons • 52 with names • 6 unconfirmed moons

41. Jupiter’s Shepherd Moons • Metis • Thebe • Adrastea • Amalthea • INNER • MOONS!

42. Saturn’s Moons • Io • Europa • Callisto • Ganymede

43. Titan Images of Io Image

44. Titan • Only moon in the solar system to have its own atmosphere • atmosphere is impenetrable to visible waves • 2nd largest moon in the solar system • Resembles early earth • Atmosphere of nitrogen and methane

45. Surface – False Color Cassini

46. Missions • Voyager • Arrived: 1980 • Studies: close fly by of Titon, • Achieves: images of rings

47. Missions • Cassini • Arrived: 2004 • Studies: saturn orbit insertion, flyby of titan. lightning • Huygen Insertion – Huygens descended onto the surface of Titan on January 14, 2005,

48. Missions – Cassini Orbit

49. Uranus!

50. Uranus’s Facts • Mythology – Named after the greek god of the sky • 7th planet from the sun • 3nd largest planet in the solar system • Ice Giant • Tilted sideways (north and south lay where other planets have their equators)
