Document Summary

Jupiter: average distance from sun: ~5 au, orbital period: ~12 years, mass: 317 me, radius: 11 re, mostly h and he, cloud top temperature: 125 k (-148 c, dozens of satellites. Europa (r = 1569 km), slightly smaller than moon (r = 1740 km) Saturn: average distance from sun: ~10 au, orbital period: ~29 years, mass: 94 me, radius: 9 re, mostly h and he, cloud top temperature: 95 k (-175 c, dozens of satellites. Titan (r = 2575 km), bigger than mercury (r = 2440 km) Classification: large (d>1500km): active and on going geology, medium (d>300km) evidence for some geologic activity in the past, small (non-spherical, many large and medium moons likely formed in a disk, many small moons probably captured. Galileo galilei (1564-1642) built a telescope and looked at the stars: most known for discovery of four most massive moons of jupiter: io (active volcanoes), ganymede (subsurface ocean), europa (large-scale tectonism),
