According to Kepler's Third Law of Planetary Motion, the square of the orbital period (T^2) of a planet is directly proportional to the cube of the semi-major axis (R^3) of its orbit. This relationship can be expressed as T^2/R^3 = constant for all planets orbiting the Sun, assuming circular orbits.
