Those who would point in the direction of Galileo as a great innovator by use of a telescope in describing the motions of Jupiter's satellites have nothing to say about the 21st century planetary version where Venus and Mercury are see to run their faster and smaller circuits of the Sun seen from a slower moving Earth. Galileo's interpretations were well deserved yet the contemporary version has been so long rejected in this forum while only being half explained elsewhere.

Mercury was becoming brighter towards the end of the time lapse footage for reasons most students would understand and the use of Jupiter's satellites would be complimentary to the planetary version of the same motions.

Galileo did not correctly identify that planetary direct/retrograde motions are not homogeneous so a necessary partitioning is required. The key yo the faster moving planets is accounting for the change in position of the background stars thereby allowing the faster planets to move faster than the change in position of the stars when travelling in front of the Sun and in the opposite direction when traveling behind the Sun.

Nobody here has the stature for anything else only historical revisionism using historical characters yet have no appreciation for the technical arguments held by these people.
