It seems to me gravity alone cannot explain the earth circling the sun. That is an unstable model. Any minor deviation and the earth would spiral into the sun or sail off into space.
I expect there is a force that pushes earth away from the sun. The earth's orbit would be the point where this force balances gravity. Looking forward to the discussion about magnetic forces!
For the moment, I am not writing about why the earth revolves around the sun. This is a very important topic that will be touched upon in numerous future posts. Even the great French mathematician Pierre-Simon Laplace, who did the most to mathematize Newton's work, could not create a stable model of the solar system. Johannes Kepler's approach was quite different: he assumed that the solar system was resonant, which I understand to mean self-stabilizing. Furthermore, in Kepler's system, the orbits of the celestial bodies are not random. My intuition is that if we assume the celestial bodies to be charged, then as they approach each other, mutual exchange of charged particles could help adjust their orbits, allowing the latter to remain stable. It may well be, if André Koch Torres Assis, starting from Wilhelm Eduard Weber's equations on electricity, is correct, that gravity is a fourth-order phenomenon of electricity. As I said, there is a lot to be written about.
