Physical considerations of variable orbital motion
From Gerald Kelleher@21:1/5 to All on Tue Aug 22 01:01:14 2023
The discovery that the Sun travels through space should have accompanied the visual affirmation of external galaxies implying that our solar system is also a component of a galactic structure.
Another implication is that the energy moving the Sun in an organised path around the galactic centre would also affect the orbital motion of the planets as they run part of their circuits in the direction of galactic orbital motion and part of the orbit
traveling in the opposite direction.
The axiom that planets run faster the closer to the Sun they are comes into play here. As the Earth moves in the direction of our solar system's galactic orbital motion it moves faster at perihelion and slower at aphelion.
Orbital motion is not there to affirm late 17th-century geometric treatments, it is there to be advanced with more expansive observational data and more perceptive abilities as described in outlines here.
