How much energy does the asteroid receive from the sun per unit time? How hot must it be to radiate this energy away at the same rate?

HINT: You'll need the equations for flux and the luminosity of a blackbody.

$$P = \sigma T^4$$ where P is the total power.
$$\phi = P/A = \frac{\sigma}{4\pi d^2}T^4$$
