Answer:
The third law of Kepler describes the proportionality of the orbital period and the semi-major axis of the orbit.
The square of the period of the orbit of a planet is proportional to the cube of the semi-major axis of the orbit.
The equation of the law is as follows:
[tex]\frac{T^2}{a^3}=constant[/tex]
Where [tex]T[/tex] is the period and [tex]a[/tex] is the semi-major axis.
