AS101 Lecture Notes - Roche Limit, Methane, Orbital Period
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. Many smaller objects (less than a few hundred km across) orbit jupiter. Closer than the galilean four include amalthea, metis, adrastea, thebe. Pressures, hydrogen becomes an like a liquid metal. Not naturally occurring on earth, but under high pressures you can duplicate this to earth. behaviour. Helps explain why jupiter has such a high magnetic field. Jupiter has an aurora because of its magnetic field. Patterns of wind can be understood based on the interaction of convection and the planet"s rotation, much as on earth.
