Kepler's three laws of planetary motion can be described as follows:
1. Law of Ellipse - The path of the planets around the sun is elliptical in shape, with the center of the sun being located at one of the two foci of the ellipse.
2. 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.
3. Law of Harmonies - The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun.
