Effects on the Environment The most significant impact of Earth's precession is on the distribution of solar radiation, or insolation, across different latitudes. Earth's Specific Cycle For Earth, this axial precession period is approximately 25,772 years.
Precession Period Nutation and Orbital Eccentricity Explained
As the axis wobbles, the timing of the seasons relative to Earth's position in its orbit changes. Furthermore, precession should not be confused with the slight changes in the shape of Earth's orbit around the Sun; these are distinct orbital variations that interact with the precession of the equinoxes to modulate the severity of seasons.
These long-term shifts in seasonal intensity are believed to influence the pacing of climatic cycles and the retreat or advance of ice sheets over millennia. During this cycle, the direction in which the axis points gradually shifts, altering the position of the celestial poles in the sky.

About 12,000 years from now, the axis will have preposed enough that the bright star Vega will assume the role of the North Star. Mechanics of Axial Wobble The fundamental cause of this motion lies in the gravitational influence of other celestial bodies.
