The solar system below was designed to work out which planet is most often closest to Earth. It was assumed that circular orbits instead of eliptical orbits would somehow be okay. The speed of each planet is inaccurate. It would be interesting to know if inaccurate planet speed would change the accuracy. For example if two planets had a speeds such that they were always next to each other, that would give really inaccurate results, but that seems unlikely to happen. After scaling the radius and orbit of each planet, the planet radius is increased 10000x as to make the planet visible on the screen.
