@fizixfan A beautiful depiction of everything I've been taught over the years brought together very nicely... and yet it appears to be missing part of the "3D" aspect of motion. While you show the "orbital wobble" around the axis of the Sun and Earth, it's missing on the Moon (as well as the Moon's North Pole, a minor issue yet still incomplete), but on the bigger scale, you've not included the wobble on the Galactic North Pole. I cannot imagine that it would be totally stationary and locked when everything that it's comprised of isn't stationary at all, even if we don't yet know the amount of the angle of the galactic wobble (however small that may be). Also not shown is the effect of that wobble in regards to the path of the Sun around the Milky Way, or the effect that it would have on the Galactic Plane of the Milky Way itself. Perhaps a "thickening/thinning" of the path lines to show the "to/fro" of the motion that can't be shown with up/down pathing, and provide a 3D view of the Earth/Moon orbits? It all really simply depends on just how accurate you want it to be, but even if we don't know the numbers, we can show the motion with a "?", and let someone fill that in at some future date. I'm sure at some point, some mathematician will figure out ALL the numbers and win some kind of award for it, but since it takes 240Million years for a galactic revolution, it may be a while.
