The temperature (T) of a planet (ignoring any other sources of heating) is solely a function of how far away the Sun is (d) and how bright it is (luminosity, L); planets are also reflective, so the light that they reflect (A) will not change their temperature: 1/4 L(1-A)) 16ond2 T = o here is just a constant, like T. 10. How much hotter is the Earth at perihelion than at aphelion? To answer this, solve for the 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 the previous problems. %3!
