What structural pattern is evident when comparing the densities of the Galilean moons based on their distance from Jupiter?
Answer
The closer a moon is to Jupiter, the higher its density and differentiation
The data shows a stark pattern: Io (innermost) has the highest density ($\sim 3.53 \text{ g/cm}^3$), while Callisto (outermost) has the lowest ($\sim 1.83 \text{ g/cm}^3$). This is tied to internal heating.
