WebFeb 27, 2024 · Milankovitch cycles include the shape of Earth’s orbit (its eccentricity), the angle that Earth’s axis is tilted with respect to Earth’s orbital plane (its obliquity), and … Web"Obliquity and Precession for the Last 5000000 Years": For the past 5 million years, Earth's obliquity has only varied between 22° 02' 33" and 24° 30' 16". So whatever the cause it seems the Earth's angle is quite stable. Without our 23° we wouldn't have seasons or longer nights and shorter days throughout the years.
