      Question

      Who enunciated the laws of planetary motion?

      A Nicolaus Copernicus Correct Answer Incorrect Answer
      B Johannes Kepler Correct Answer Incorrect Answer
      C Isaac Newton Correct Answer Incorrect Answer
      D Galileo Correct Answer Incorrect Answer

      Solution

      Kepler's laws of planetary motion are three scientific laws describing orbital motion, each giving a description of the motion of planets around the Sun. The laws are: the orbit of every planet is an ellipse with the Sun at one of the two foci; a line joining a planet and the Sun sweeps out equal areas during equal intervals of time; and the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
