Of all the planets, Mars was the one which is most accessible to the different perspectives involved in a moving Earth and a Sun-centred system.


Kepler's non-geocentric plotting of the motion of Mars as seen from the faster moving Earth is perhaps one of the best descriptions although present experimental theorists, beginning with Newton, imagine it is a geocentric description-

"Copernicus, by attributing a single annual motion to the earth,entirely rids the planets of these extremely intricate coils, leading the individual planets into their respective orbits,quite bare and very nearly circular. In the period of time shown in
the diagram, Mars traverses one and the same orbit as many times as the 'garlands' you see looped towards the centre, with one extra, making nine times, while at the same time the Earth repeats its circle sixteen times " Kepler Astronomia Nova 1609

Contemporary imaging lovingly re-creates the sequential loops and their variations with each pass of the Earth-

This fixed field of background stars solution has existed for 500 years, however, now with a satellite peering into the inner solar system where the central/stationary Sun exists along with the background behind the Sun, the motion of Mars comes back
into focus.

Mars moves from left to right a lot slower than Jupiter and Saturn for the obvious reason that its motion is faster so while the Earth's observational input causes the apparent change in the position of the stars from left to right using the stationary
Sun as the new reference for this new type of astronomy, its actual movement is faster from right to left than the planets further out from the Sun.

I would hope that it will make it into star parties and eventually into classrooms where it will give students a fresh look at astronomy beyond just identification and magnification as they begin to exercise their perceptive faculties.
