This isn't about Newton being wrong but rather all that is good about astronomy exists like scattered leaves throughout the internet so that a narrative has emerged where the external illusionary loops of the outer planets differ from the actual loops of the inner planets as they run their annual circuits around the Sun.

Kepler's rendition of Mars as seen against the background stars doesn't work for inner planets and therein lies a flaw that I have addressed since the inception of Sun centered reasoning -

The hapless empiricist who follows Newton's absolute/relative space and motion (and still do as seen from a nuisance poster) can't spot the attempt to double model the same observation based on an idea that retrogrades are seen from Earth (relative space and motion) disappear with a Sun centered view (absolute space and motion). Of course this generated the silly attempt to equate Earth based observations with Sun based observations -

"That the fixed stars being at rest, the periodic times of the five primary planets, and (whether of the sun about the earth, or) of the earth about the sun, are in the sesquiplicate proportion of their mean distances from the sun.... for the periodic times are the same, and the dimensions of the orbits are the same, whether the sun revolves about the earth, or the earth about the sun." Newton

People who can't work it out and who are paid to call themselves astronomers have no qualifications much less all the linguistic rubbish of relativity built on exploiting Newton's absolute/relative jargon .
