Explain Keplers laws or Keplers first-second-third law

Explain Keplers laws or Keplers first law, second law and third law?

Kepler's laws (J. Kepler)

Kepler's first law: The planet orbits Sun in an ellipse with the Sun at one focus.

Kepler's second law: The ray directed from the Sun to a planet sweeps up out equivalent regions in equivalent times.

Kepler's third law: The square of a period of a planet's orbit is proportional to the cube of that planet's semi major axis; the constant of proportionality is the same for all planets.
