The average densities of the Galilean satellites of Jupiter follow which pattern with increasing distance from the planet?

Question

Quizplus · Accepted Answer

The Galilean satellites of Jupiter follow a pattern in which the average density decreases with increasing distance from the planet. This is because the further away a satellite is from Jupiter, the less effect its gravity has on its composition, and the more likely it is to be composed of lighter materials such as ice rather than heavy metals. The lightest and most distant satellite in the group, Callisto, has an average density of only 1.83 g/cm³, while the closest and heaviest, Io, has an average density of 3.53 g/cm³.
