The correct statement that describes Kepler's third law of orbital motion is:

**The square of the orbital period is proportional to the cube of the semi-major axis.**

In mathematical terms, this is often expressed as:

\[ T^2 \propto a^3 \]

where \( T \) is the orbital period and \( a \) is the semi-major axis of the orbit.
