The temperature of earth is maintained by a dynamic equilibrium between Sun and Earth Sun and Earth can be assumed to be black bodies If the power output of sun is doubled by changing the temperature equilibrium temperature of earth also doubles If the radius of sun doubles without changing its power output its surface temperature would become 1 2 times of initial temperature If the radius of earth doubles without any change in sun its equilibrium temperature would become 2 times If the distance between earth and sun would decrease by a factor of 2 the equilibrium temperature of earth would become 2 times
