Question

Quizplus · Accepted Answer

Kepler's third law states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. Newton derived this law from the law of gravitation, which applies to all situations where two objects orbit each other solely under the influence of their mutual gravitational attraction. Therefore, option A is correct. Option B is incorrect because the law applies to any two objects orbiting each other, regardless of their respective masses. Option C is also incorrect because the law is valid for any distance between the objects. Option D is incorrect because the law applies to any two objects, not just planets orbiting the Sun.
