(a) Diagram showing graph of the equilibrium temperature vs. distance from the Sun. (b) Temperature variations across the surface of the Earth, as shown in near infrared images from space.This image is at a wavelength of 1 ^m from the Galileo spacecraft at a distance of 2.1 million km. Lighter areas are giving off more infrared emission. [(b) NASA]

important effects of radiative transfer in the atmosphere.

We can also do this calculation for planets at any distance from the Sun, and we obtain the results shown in Fig. 23.9(a). Here we present a graph, in which we show the equilibrium temperature at different distances, and note the locations of the planets. Notice how this temperature decreases with increasing distance.
