Milankovitch cyclesFrom Wikipedia , the free encyclopediaMilankovitch cycles are the collective effect ofchanges in the Earth's movements upon itsclimate, named after Serbian civil engineer andmathematician Milutin Milankovi . Theeccentricity, axial tilt, and precession of theEarth's orbit vary in several patterns, resultingin 100,000-year ice age cycles of theQuaternary glaciation over the last few millionyears. The Earth's axis completes one full cycleof precession approximately every 26,000 the same time, the elliptical orbit rotates,more slowly, leading to a 21,000-year cyclebetween the seasons and the orbit.
Saturn. As the eccentricity of the orbit evolves, the semi-major axis of the orbital ellipse remains unchanged. From the perspective of the perturbation theory used in celestial mechanics to compute the evolution of the orbit, the semi-major axis is an adiabatic invariant. According to Kepler's third law the
