But an object like Enceladus is essentially a giant drop of water with an ice coating. It's round because it's made of ice, when an object of similar mass made of rock would not be. I'm not sure, but tidal forces probably play a role in keeping it round as well. How could we determine which objects are round through isotropic pressure?
