Figure 2: The main characteristics of the Earth's motion in space that affect the radiation it receives from the Sun. Left: the degree of ellipticity of the orbit around the sun, the change in this feature is characterized by cycles of about 400,000 and about 100,000 years. In the center: the degree of inclination of the earth's rotation axis towards the sun, the change in this feature is characterized by a cycle of about 40,000 years. On the right - the direction to which the Earth's rotation axis points in space, the change in this feature is characterized by a cycle of about 20,000 years. Source: Wikimedia.
