To determine which option describes Kepler's third law of orbital motion, we need to understand what the law states and then match it with one of the given options.
Kepler's third law of orbital motion states that the square of the orbital period (T) of a planet is proportional to the cube of its average distance (a) from the sun (or the center of mass). The formula for Kepler's third law can be expressed as:
T^2 ∝ a^3
So, the option that correctly describes Kepler's third law of orbital motion is:
T^2 ∝ a^3.
