Document Summary
1 jupiter: read chapter 11 in the textbook, exercises: do all review and discussion and all conceptual self-test , basic properties. Largest planet in the solar system very di erent from the terrestial worlds. 317 earth masses, 11. 21 earth radius, density 1. 33 gm/cm3. Many moons 16 over 10km in diameter, 63 known. Orbital parameters 5. 20 au, 11. 86 years. Fastest rotation rate in solar system 9hrs 55mins. Rotation di erential equatorial regions rotate faster than polar regions. From earth can easily see four large moons (galilean moons: atmosphere of jupiter. Two dominate features cloud bands and the great red spot. Bands, pale yellow, light blues, browns, reds. Great red spot giant hurricane . Atmospheric compoistion h2 (86. 1%), he (13. 8%), trace amounts of methane, ammonia, water vapor. No surface increasing pressure to the core. Strong gravity prevented the atmosphere from escaping hydrogen and helium remain. Voyager and other satellites observation convection. Zone upwelling material (gasses), high pressure.
