1500K -- metal oxides
1300K -- metallic iron/nickel
1200K -- silicates
175 K  -- H2O ice
120 K -- CH3 (methane) ice
Much of difference between terrestrial and Jovian planets
due to non-condensation of light atoms (H) close to sun
 Without H (80% of mass), can’t grow large
® no fast gravitational growth, get only rocky and metallic
