Kepler’s third law states that square of period of revolution (T) of a planet around the sun, is proportional to third power of average distance r between sun and planet i.e T^2 = Kr^3 here K is constant. If the masses of sun and planet are M and m respectively than as per Newton’s law of gravitation force of attraction between them is F = r^2/GMm, here G is gravitational constant The relation between G and K is described as
