Chapter Summary Chapter 23-24: Jovian planets (don’t forget to find definitions at the end of the book, in the glossary and draw pictures!!!!!) 1. Know general information about all the jovians comparatively. 2. Jovians are mostly gases (H, He, H 2 O, CH 4 , NH 3 ); the rest = icy + rocky compounds 3. Have no solid surface : gases --> liquid & solid at high pressure 4. Have ring systems and many moons 5. Formed faster (less than 3 – 5 Myrs) than terrestrial planets. large enough to accumulate gas directly from the solar nebula 6. They are far from the Sun 7. Interiors are HOT! 8. They emit more energy than they receive from Sun except for Uranus Jupiter may still be contracting; Saturn helium rain Uranus does not emit excess energy Neptune emits twice as much as it gets; still contracting ?? ) 9. Know general information about each jovian separately; for example:

Unformatted text preview: a. Jupiter is the largest and contains ¾ of total Solar Syastem planetary mass b. Saturn has the largest set of rings c. Uranus’ axis of rotation is in the plane of the Solar System d. Neptune and Pluto cross orbits I am sure you can find other interesting info when you read your text. 10. differential rotation 11. oblate 12. frost line 13. rotation rates of jovians are fast; Jupiter’s is about 10 hr 14. storms; Great Spot, cloud belts, convection 15. magnetic fields 16. Jupiter and Io interaction 17. rings around jovians; origin, temporary, composition (icy particles) 18. Roche limit 19. Shoemaker Levy comet 20. Jupiter’s moons; history, general composition (ice and rock) 21. Saturn’s rings: composition is mainly ice particles, thin, at the equator 22. Saturn’s Gap moons, Shepard moons...
