Planetary Motion is a simple simulation that displays the motion of an object which is orbiting a planet.

Newton’s inverse-law of gravitation allows users to reformulate this motion in modern terms using the equations for a massless test particle about a particle of mass M located at the origin. 

M is the combined mass of the Sun and the planet and G is the universal gravitational constant.

The xy-coordinates for the massless test particle are the relative position of the planet with respect to theSun in this two-body approximation of the solar system.
The initial values for x and y and its derivatives must be taken from direct astronomical observation.In this simulation, they are chosen arbitrarily.
