7.5: The Gailean Moons of Jupiter

Callisto is unique among the planet-sized objects of the solar system in the apparent absence of interior forces to drive geological change. You might say that this moon was stillborn, and it has remained geologically dead for more than 4 billion years (Figure (PageIndex{1})).

Shape of the Planets in the Solar System

The shape of a space object depends on its mass: the bigger it is, the more its own gravity pulls it into a more round form. Saturn is the most oblate planet in the Solar System: as it rotates the fastest of all, its equatorial bulge is the thickest. Mercury and
