Earth aphelion au
WebFor Earth, the orbital eccentricity is only 0.017, so perihelion and aphelion are at 0.983 AU and 1.017 AU respectively. Thus, the change in flux from perihelion to aphelion would be only. Flux sun (perihelion)/Flux sun (aphelion) = (1.017 AU / 0.983 AU) 2 = (1.034) 2 = 1.070 and the consequent change in temperature is only Webaphelion, in astronomy, the point in the orbit of a planet, comet, or other body most distant from the Sun.
