where is the "areal velocity".
This is also known as the law of equal areas. To understand this let us suppose a planet takes one day to travel from point A to point B. The lines from the Sun to points A and B, together with the planet orbit, will define an (roughly triangular) area. This same area will be covered every day regardless of where in its orbit the planet is. Now as the first law states that the planet follows an ellipse, the planet is at different distances from the Sun at different parts in its orbit. This leads to the conclusion that the planet has to move faster when it is closer to the Sun so that it sweeps an equal area.
Third Law
"The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit."
Symbolically:
where P is the orbital period of planet and a is the semimajor axis of the orbit.
Third Law published by Kepler in 1619, This captures the relationship between the distance of planets from the Sun, and their orbital periods.
