How does the study of Earth's Moon inform our understanding of other moons?

The answer key says that "every moon necessarily orbits a planet in the system" although the sufficient indicator "any" is qualifying "moon." ... orbital radius, around planets with the same mass, will have the same orbital speed. Remember that this relationship only applies in the case of circular orbits ... Space is huge, and even our immediate environment is gigantic.
