Answer:
The mentioned situation is the basis of the Kepler's three laws of planetary motion which can be described as follows:
(1) Kepler's first law states that the path of the planets about the sun used to be elliptical in shape, with the center of the sun being located at one focus.
(2) Kepler's second law states that if an imaginary line drawn from the center of the sun to the center of the planet then the imaginary line will sweep out equal areas in equal intervals of time.
(3) Kepler's third law states that the ratio of the squares of the periods of any two planets used to be equal to the ratio of the cubes of their average distances from the sun.
