Orbital mechanics require that the duration of the seasons be proportional to the area of Earth's orbit swept between the solstices and equinoxes, so when the orbital eccentricity is extreme, the seasons that occur on the far side of the orbit (aphelion) can be substantially longer in duration. Northern hemisphere autumn and winter occur at closest approach (perihelion), when Earth is moving at its maximum velocity—while the opposite occurs in the southern hemisphere. As a re… WebProxima Centauri b is a super Earth exoplanet that orbits an M-type star. Its mass is 1.07 Earths, it takes 11.2 days to complete one orbit of its star, and is 0.04856 AU from its star.
