Compare Titan to Rhea. Estimate the strength of surface gravity on Titan compared to the gravity on Titan. How does this affect the possibility of an atmosphere on each?
Use g=GM/R2
Titan Radius: 2,575 km, Mass: 2.31 x 1021 kg
Rhea Radius: 764 km, Mass: 1.35 x 1023 kg
Density is mass per unit volume. Granite rock weighs about 2.7 g/cm3, water weighs about 1.0 g/cm3. Knowing their sizes, how might you determine whether Europa or Ganymede is hiding a large liquid water ocean beneath an icy crust?
