This is how Newton resolved retrogrades which otherwise is easy to
understand and enjoyable
"For to the earth they appear sometimes direct, sometimes stationary,
nay, and sometimes retrograde. But from the sun they are always seen
direct.." Newton
No doubt that many like AB would approach this forum with good faith
and the assumption that you are legitimate astronomers who inherited
the Copernican insight and that you would present it as a perfectly
understandable and enjoyable insight that teenagers would love.
The fact is that planetary heliocentric motions are seen direct from
the Earth's orbital motion and this dawning realisation is still as
spectacular today as it was for Kepler and Galileo irrespective of the
foolish Newtonian resolution.Knowing why Mars is presently appearing to
move backwards as plotted on a different day against the stellar
background is a wonderful way to acknowledge that our planet is
overtaking the slower orbital motion of Mars which is on an outer
heliocentric circuit.
Pity you cannot savor the original Copernican solution for apparent
retrogrades.
