AS101 Lecture Notes - Lecture 17: Dwarf Planet, Flattening, Metallic Hydrogen
Document Summary
The outer solar system: jovian planets, one dwarf planet, and their moons. Hydrogen gas - outer layer where pressure isn"t as high for ice giants: Mantle - icy, made of water and other ices. Atmosphere - the mantle materials become gasses. Outer atmosphere - thin layer at the very outside where clouds are. All of these planets have a magnetic field. ***uranus and neptune have magnetic fields that do not align with their rotational axis. All jovian planets are oblate: oblateness: - the flattening of a spherical body, usually caused by rotation. Liquid and gaseous bodies are flatter than solid rocky bodies. Fraction by which the equator diameter is greater than the polar diameter, plus density, helps interior models. All of the jovian planets have rings. Largest planet in the solar system: contains 71% of all planetary matter in the solar system. Longest lived storm in the solar system o 300 years for the great red spot.
