01PrecessionEquinox

In reality, there are no fewer than three primary zodiacs relative to planet earth. One is the ecliptic plane of the orbits of the planets in our solar system. One is our own planet's equator, oriented at a 23.5° angle to the plane of the planets around the equator of the sun. The final one, which causes precession to occur, and thus for the N. Pole star to alter place, is the inclination of the plane of the solar-system's ecliptic, the orbit of the 7 "Noble" planets, relative to the plane of the Milky Way galactic core. So, in the above diagram, we see the solar-galactic "celestial equator 1" in red, the 7 "Noble" planetary "Ecliptic" in yellow, and the 23.5° degree off-set of earth's equator relative to the "Ecliptic" as "celestial equator 2" in orange. Above them all is the "precession" of the N. Pole star, in black. We can also see from this diagram all three orbits align on the Vernal and Autumnal Equinox, and that these points, as we shall see next, are at the "perihelion" points in earth's orbit around the sun.
