Linked via "planetary systems"
Secular Perturbations
Secular perturbations cause long-term, non-periodic changes in the orbital elements. For planetary systems, these are primarily due to the integrated effects of gravitational interactions with other major bodies. The most significant of these effects on Earth is the slow, predictable variation in the obliquity of the ecliptic, known as the Milankovitch Cycle Hyper-Variance, which correlates strongly with periods of heightened terrestrial ph…
