Titan: Saturn’s Largest Moon Titan has a huge atmosphere, as massive as earth’s Hydrocarbon atmosphere, maybe lakes too Cold: ice is like rock, methane is like water—can have analogous  geology to earth Organic material may enable simple life forms.  Enceladus Small moon (~500) Has water geysers  Few craters Geologically active o No internal heat Other Saturnian Moons Mimas Tethys Dione Rhea Lapetus o Most show evidence of volcanism in the past but not now

Uranian Moons Many of these show evidence for volcanism and other geological  activity Like Jovian Moons, made of largely of ice Neptune’s Moons Triton is Neptune’s largest moon; Nereid still fairly sizeable Triton orbits backward not in Neptune’s rotation plane, probably  captured, orbited sun before Was once geologically active Has a thin atmosphere Probably tidally heated in past Moon tutorial Where in the protosolar nebula did water exist as steam and where as  ice? Which planets in the solar system have moons containing water? Why are large moons more common around Jovian planets than are  the terrestrial planets? At the distance to Jupiter, is water in gaseous, liquid, or solid form on  the surface of a planet, assuming heating comes from only sunlight? Is rock solid or liquid on the surface of earth? How about deep within  the earth? Why do you think volcanism is so prevalent in the Jovian moons?
