#### Explanation:

This is from the Law of Harmonies of Johannes Kepler which states that:

The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun.

*The more distant the planet is, the longer it will take for it to complete one revolution.*
