    orbits of all the planets are elliptical with the Sun at one focus of the ellipse. An ellipse is a somewhat flattened circle. It is a closed curve in which the sum of the distances from any point on the ellipse to foci (two points inside) is constant.

    Law of ellipse

  • 2

    a line joining a planet and the Sun sweeps out equal areas in space in equal intervals of time. Thus, a planet moves fastest when it is nearest to the sun.

    Law of equal areas

  • 3

    the square of a planet’s orbital period (years) is proportional to the cube of the semi major axis of its orbit (in astronomical units or AU) or 𝑃 2 = 𝑎 3. Thus, the larger the orbit’s size, the longer it takes to orbit the sun.
