    T2=r In the form of Kepler’s law that can use to relate the period T and radius of the planet in our solar systems

    Explanation:

    Kepler’s third law:

    • Kepler’s third law states that For all planets, the square of the orbital

         period (T) of a planet is proportional to the cube of the average orbital    radius (R).

    • In simple words T (square) is proportional to the R(cube) T²2 ∝1 R³3
    • T2 / R3 = constant = 4π ² /GM

          where G = 6.67 x 10-11 N-m2 /kg2

            M = mass of the foci body
