Document Summary
Voyager 1&2: determine h/he atmos, winds, auroras (has magnetic field) Saturn: almost same composition as jupiter but less dense. Weird, cause saturn has less h (lighter) and more heavy elements however its due to matter of relative compaction: saturn radiates 1. 8x as much energy it receives from sun (hot inside) Atmosphere: gradual change from gaseous atmos to liquid planet, saturn no surface. Belt zone: appears to arise in same way as jupiter. Belts: lower clouds formed by sinking gas: dramatic diff b/w jupiter and saturn is wind, jupiter wins bound each of belt/zones but saturn has fewer winds yet stronger. *only planet to have perfectly symmetrical magnetic field: dynamo uncertain but probably interaction between core and metallic hydrogen inner mantle, magnetosphere efficient deflector of solar wind. Saturn"s rings: galileo discovered saturn but huygens discovered rings. Huygens also spotted saturns largest satellite-titan: order of saturns rings: d, c, b, a, f, g and e, f, g (faint narrow rings)
