Orbital eccentricity refers to the shape of the Earth's orbit around the sun, and in the Milankovitch theory, it is suggested that variations in this eccentricity can have an impact on the Earth's climate over long time periods. Specifically, a more elliptical orbit would result in greater variations in the amount of solar radiation received by the Earth at different times of the year, potentially contributing to the onset of ice ages or other climate shifts.
