Thank you for posting this. I wonder if anyone has made a physical galactic orrery. It seems that the concept is used in the video game Warhammer.
Something implicit in the diagrams of the galactic plane but not explicitly stated is that the solar system travels clockwise (retrograde) around the galaxy [0]. I find this unexpected as I thought the same "right hand rules" of planetary motion [1] were somehow connected to those of electromagnetism [2] and would apply upwards in scale.
The Sun follows the solar circle (eccentricity e < 0.1) at a speed of about
255 km/s in a clockwise direction when viewed from the galactic north pole at
a radius of ≈ 8.34 kpc about the center of the galaxy near Sgr A*, and has
only a slight motion, towards the solar apex, relative to the LSR.
