Nocturnus AD - Procession of the Equinoxes

Moving westward in the sky
Along the ecliptic plane, gravity induced axial change
Motion of the equinoxes
Relative to fixed stars, opposite of the Sun
Gradual shift in polar motion, changes in the alignment

Wobbling rotation, equatorial bulge, inertial space, planetary precession
Gravitational force, diurnal motion, celestial poles, axial tilt

Changing of the polar positions, over 26,000 years, it’s The Precession of The Equinoxes

Cycle of the seasons
Change over time
The Earth's obliquity
Of the orbital plane
Circumpolar stars, celestial poles, stationary points, the zenith angle.
Astronomical horizon, vertical directions, force of gravity, opposite of nadir.
Precessional eras, of constellations, Kochab and Pherkad, Guardians of The Poles
