"Mars undergoes Milankovitch cycles that are much more extreme [than those of Earth ... WebMar 27, 2024 · But the effect is much less pronounced on Earth because of Earth's lower eccentricity (~0.017 vs. ~0.093 for Mars, which causes a 6.5% difference in solar radiation intensity at perihelion vs. aphelion on Earth, and 30% for Mars). I think that explains the wording of the Wikipedia quote.
