Using Google Sketchup I created this 3D model of 7 Wandering Stars (Planets), the Sun and Moon. This video represents the Sun, Moon and 7 said Planets for two 28 day Lunar Cycles, and is accurate to within 10° of arc during the first few frames for January 14, 2016. But is not an accurate representation of time. NOT TO SCALE. This 3D model is not meant to be an entire cosmological model. The Moon slowly lags behind the Sun until it surpasses it, this creates Lunar Phases. If you observe Mercury (small and red), you can see its retrograde motion throughout the animation. In the beginning Mercury is near the Sun then moves away, reaches its furthest point and moves back toward the Sun (retrograde), and surpasses it. Venus also displays retrograde with relation to the Sun but requires more time to be observed, here you can only see it moving backwards, along with all the others, progressively slower from Mars, Jupiter, Saturn, and Uranus to Neptune being the slowest and displaying minimal precession.
