hey,
there are actually three, Kepler’s laws that is, of planetary motion: 1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its orbit. As it’s the third which is most often used, Kepler’s law usually means Kepler’s third law (of planetary motion).

Law of orbits (Kepler's I Law):
Each planet moves around the Sun in an elliptical orbit with the Sun at one of the foci.
Law of area (Kepler's II Law):
The radial vector (line joining the Sun to a planet ) sweeps equal areas in equal intervals of time.
Law of period (Kepler's III Law):
The square of the time period of revolution of a planet around the Sun in its elliptical orbit is directly proportional to the cube of the semi-major axis of the eclipse.
