... Bad Astronomy . ... Bad Astronomy : The seasons are caused by the change in the distance of the Earth to the Sun. ... The change in distance of the Earth to the Sun is a very minor player. ... Well, not completely wrong; certainly the Earth's distance from the Sun has something to do with the temperature, but it is a relatively minor effect. ... Basically, the temperature depends only weakly on distance changes; the temperature goes as the inverse square root of the distance of the planet to the Sun...
