ASTR 1100 Lecture Notes - Lecture 9: Giant Planet, Orbital Period, Eugenius Warming
Document Summary
Lecture 9: the jovian planets (part i): intro. Red spots from the shadow of the moon. Has a fastest rotation on its axis. Largest magnetic field (caused by metallic hydrogen + fast rotation) => less than 10 hours a day + metallic hydrogen give its magnetic field. Four of the seven largest moons in solar system. Red spot (huge storm raging about 400 years ago). Has four largest moons => galilean moons: io (moon of jupiter): => most volcanically active in the solar system. Mass of jupiter is 5x than the moon. The tide produced by jupiter makes io very hot: europa (icy surface): => has liquid ocean due to jupiter"s tide. => warm environment + liquid ocean = water exists. => there is a volcano spitting icy water instead of hot lava. => nasa is planning to send rovers to europa in the future: ganymede (largest moon in the solar system):
