I guess it would be based on the surface material properties. Different
materials have different thermal emissivities, so picking one with a
high value would be better for cooling directly to space. Of course
these materials may be impossible to use for some reason or other, but,
whatever, that's for somebody else to figure out ;]

Sweet! That would be *so cool*! Imagine sitting out on the deck
looking up at the full moon, and all of a sudden it starts falling
towards you. If we ignore the gravitational damage to the earth
(tides, crust stresses, etc) and the fact that the earth is still
rotating, how long would you get to watch the moon before it landed
on you? The first person to answer will get a cookie(*)!
