Determining the resilience of habitable conditions on a planet with time is important to maximize our chances to detect biosignatures — and is even more crucial if we are looking for


technosignatures. However, such assessment depends on a precise estimate of the temporal evolution of stellar irradiation received by the planet, which in turn depends strongly on the


evolution of its orbital parameters, something difficult to reconstruct even for the planets of our Solar System. Pam Vervoort and colleagues have approached this problem by using a N-body


simulation coupled with a 3D climatic model.
