The temperature (T) of a planet (ignoring any other sources of heating) is solely a function ofhow far away the Sun is (d) and how bright it is (luminosity, L); planets are also reflective, sothe light that they reflect (A) will not change their temperature:1/4L(1-A)T =16σπα?o here is just a constant, like TT.10. How much hotter is the Earth at perihelion than at aphelion? To answer this, solve forthe ratio TT, where d, = r, (the perihelion distance) and d, = r, (the aphelion distance).You should have found that r, = 1.034rp. If you did not, use this new value and redo theprevious problems.
