Kepler's Three Laws:
Johannes Kepler proposed three laws of planetary motion in the early 1600s. The three laws are:
  • The Law of Ellipses: The path of the planets about the sun are elliptical in shape, with the center of the sun being located at one focus.
  • The Law of Equal Areas: An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time.
  • The Law of Harmonies: The ratio of the square of the periods of any two planets is equal to the ratio of the cube of their average distances from the sun.
