Earths 41000 year cycle
Webow many precession periods (26,000 years) are in one cycle of Earth's orbit eccentricity period (100,000 years)? How many orbit eccentricity periods did the Earth go through in the last 410,000 years? This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebSep 29, 2016 · As seen in the diagram below, the angle between Earth’s rotational axis and the normal to the plane of its orbit (obliquity) oscillates between 22.1 and 24.5 degrees on a 41,000-year cycle. It is currently 23.44 degrees and decreasing at a rate of about 0.013° per century. 22.1–24.5° range of Earth’s obliquity Image: Wikimedia. CC2.0
