One side of our asteroid is constantly illuminated by the Sun while the other side remains in the dark. Do you expect there to be a temperature difference between the light and dark sides? Explain why or why not. If the two sides are at different temperatures, how might heat transfer from one side to the other? Note that our asteroid does not have enough gravity to hold an atmosphere.
