Answer 2

First law - Every planet revolves around the
sun is an elliptical orbit, with the sun situated at any one of the foci(plural of focus) of the ellipse.
Second law - in the elliptical orbit of the planet, the line joining the centre of the planet to the centre of the sun sweeps equal areas in equal intervals of time.
Third law - the square of time period of revolution of a planet around the sun is directly proportional to the cube of the semi major axis of the elliptical orbit.
