WebA planet’s orbital eccentricity aﬀects the climate. The eccentricity makes the planet have diﬀerent dis- tances from its host star during diﬀerent parts of the year. This makes the amount of incident solar radiation that reach the planet change during the year which will aﬀect, for example, the planet’s surface temperature.
