Astronomy with Micro Station Orbit of Venus Dance of Planets

Created in MicroStation ; 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.
