Explanation:
According to the Third Kepler’s Law of Planetary motion “The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”.
Talking in general, this law states a relation between the orbital period [tex]T[/tex] of a body (moon, planet, satellite) orbiting a greater body in space with the size [tex]a[/tex] of its orbit.
This Law is originally expressed as follows:
[tex]T^{2}=\frac{4\pi^{2}}{GM}a^{3}[/tex]
Where;
[tex]G[/tex] is the Gravitational Constant
[tex]M=1.9(10)^{27}kg[/tex] is the mass of the massive (greater) body
[tex]a[/tex] is the semimajor axis of the orbit of the smaller body
