Earth's eccentricity cycle takes 100,000 years, Earth's obliquity cycle takes 41,000 years, and Earth's precession cycle takes 26,000 years. In what order does Earth complete its cycles? It first completes an eccentricity cycle, then an obliquity cycle, and much later a precession cycle. It first completes an eccentricity cycle, then a precession cycle, and much later an obliquity cycle. It first completes a precession cycle, then an obliquity cycle, and much later an eccentricity cycle. It first completes a precession cycle, then an eccentricity cycle, and much later an obliquity cycle.

The cycles of Earth's eccentricity, obliquity, and precession are fascinating aspects of our planet's movements that greatly influence its climate and environment. The order in which these cycles are completed is rooted in their lengths: the precession cycle at 26,000 years occurs first, followed by the obliquity cycle at 41,000 years, and finally the eccentricity cycle at 100,000 years. To put this into perspective, imagine Earth as a dancer twirling and tilting on a large cosmic stage. It does a quick spin (precession), then leans dramatically (obliquity), and finally glides gracefully across the floor (eccentricity)—but the dance of eccentricity takes the longest! Understanding these cycles is key to grasping the long-term changes in Earth's climate.
