Google Orrery on the birthday of Copernicus

A better and more challenging representation would have been the APOD
images which demonstrates a moving Earth rather than a mechanical
orrery -

Mathematicians rarely develop a talent for astronomy yet those images
above reflect a faster moving Earth periodically overtaking these
planets,that is how Copernicus proposed it,that is how Galileo and
Kepler understood it while mathematicians simply do not.Mathematicians
try to model planetary motions via a pernicious and false use of
retrogrades hence the orrery/orbital mechanics spiel and they don't
even comprehend their own vicious strain of empiricism which defines
this preventable tragedy

"For to the earth planetary motions appear sometimes direct, sometimes
stationary, nay, and sometimes retrograde. But from the sun they are
always seen direct,..." Newton

Any person of reasonable intelligence can comprehend what retrogrades
are and how they refer to a moving Earth and they will certainly know
almost instantly why that attempt by Newton which leads to absolute/
relative time,space and motion is rubbish,not valid in any way but
simply unusable and worthless.
