#Kepler's_law_of_planetary_motion__Kepler's_law  (astronomy) one of three empirical laws of planetary motion stated by Johannes Kepler
  supertype:  law_of_nature__law  a generalization that describes recurring facts or events in nature: "the laws of thermodynamics"
  subtype:  Kepler's_first_law  a law stating that the orbit of each planet is an ellipse with the sun at one focus of the ellipse
  subtype:  Kepler's_second_law__law_of_areas__law_of_equal_areas  a law concerning the speed at which planets travel; a line connecting a planet to the sun will sweep out equal areas in equal times; "Kepler's second law means that a planet's orbital speed changes with its distance from the sun"
  subtype:  Kepler's_third_law__harmonic_law  a law stating that the ratio of the square of the revolutionary period (in years) to the cube of the orbital axis (in astronomical units) is the same for all planets
