But during the Milankovitch Cycle, it varies from 22.1° to 24.5° and takes 40,000 years to complete a full cycle. Earth’s changing obliquity doesn’t alter the total amount of incoming solar radiation. Instead, it affects the geographic distribution of where sunlight hits the Earth.

WebAxial tilt (obliquity) The angle of the Earth's axial tilt (obliquity) varies with respect to the plane of the Earth's orbit.
