AS101 Lecture Notes - Lecture 18: Roche Limit, Galilean Moons, Metallic Hydrogen
Document Summary
Contain a lot more hydrogen and helium, and hydrogen-containing compounds like water, ammonia, methane (a. k. a. All have rings made up of icy/rocky debris. (saturn"s are the most prominent. ) In summary, you could almost say that it"s as if each one of the. Jovian planets forms its own miniature solar system. Surface temp (top of cloud layer): -108 c. 90%hydrogen, 10% helium, less than 1% other stuff. Moons of jupiter: other moons: many smaller objects (less than a few hundred km across) orbit jupiter, closer than the galilean four include amalthea, metis, Internal structure: metallic hydrogen: under high pressures, hydrogen becomes an electrical conductor and behaves like a liquid metal, liquid metal creates an extremely strong magnetic field compared to earth. Patterns of wind can be understood based on the interaction of convection and the planet"s rotation, much as on earth.
