By digitizing the coordinates Kepler provides, modern enthusiasts can recreate the exact errors Kepler made. They can see precisely where a transcription error in Tycho’s data led Kepler down a wrong path, or how he used the "vicarious hypothesis" (a mathematical trick to approximate the truth) to inch closer to the correct ellipse.
Why does the planet move in this way? I propose that there is a force (an anima motrix ) emanating from the Sun. This force is magnetic in nature. The Sun rotates on its axis, and this rotation sweeps the planets around. But the planets themselves have their own magnetic poles. One pole is friendly to the Sun, the other is unfriendly. As the planet orbits, these poles turn, sometimes attracting the planet to the Sun (perihelion) and sometimes repelling it (aphelion). This magnetic interaction stretches the orbit into an ellipse.
