A recent conversation brought up the issue of variable orbital speed and how a better approach can be found to explain this feature of planetary orbital motion.
These types of compositions are enjoyable as a standalone topic, for although it lacks the usual cause and effect between planetary dynamics and the Earth sciences that I normally engage in, the components are there anyway.
The axiom that planets closer to the Sun move faster is one component. The Sun has a forward motion through space in its galactic orbital capacity is another component.
Whether the planets orbit the Sun or the planets move with the Sun in its galactic orbital motion as a primary motion is not really important; all that matters is that these two components exist in isolation and in combination.
It would be the forward motion of the Sun alone through space that affects the variable orbital speed of the planets as the planets partly spend their orbits moving with the Sun and part travelling in the opposite direction.
The fastest and slowest speeds annually of the Earth indicate the direction of galactic orbital travel from a line drawn through the Sun from those annual milestones.
Omitting any galactic orbital component and that the Sun does actually move is as unusual as not recognising the Sun is central to all planetary motions when the solar system is isolated as an entity.
Isn't the Sun orbit around the Earth?
That what I learned in Church!
