Kepler's Third Law of planetary motion primarily relates the orbital period of a planet to its average distance from the Sun. The correct variables involved in understanding this law are:
- **Orbital period (T)**: The time it takes for a planet to complete one full orbit around the Sun.
- **Distance to the Sun (a)**: Usually expressed as the semi-major axis of the orbit.
In its simplest form, Kepler’s Third Law states that the square of the orbital period (T²) of a planet is directly proportional to the cube of the semi-major axis of its orbit (a³).
Thus, the most relevant variables for Kepler's Third Law are **orbital period and distance to the Sun**. Other options, such as rotational velocity or eccentricity of orbit, are not directly related to this particular law.
