#T^2=a^3#

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.
