Astronomy with MicroStation Orbit of Venus Dance of Planets

Created in MicroStation http://www.Bentley.com ; this clip was made to mark the recent conjunction of planets Venus, Jupiter and Mercury. It shows a single planet's (Venus) motion as observed from the Earth. First, the idealized or 'synchronized' motion with Earth's year shortened by about 2 hours 42 minutes. This gives 13 orbits of Venus in 8 years, giving a CLOSED Epicyclic pattern repeating every 8 years. Then the actual periods are used with alter the pattern that would take a very long time to close (and hence repeat). Finally the simple arithmetical explanation of LCM (Least Common Multiple) underlying the rarity of astronomical phenomenon is given.
