The Daughters of the Moon is a 1968 short story by Italo Calvino. In it, the narrator describes the effect of a dying and crumbling moon on an Earth-like planet. You can read it online here. It begins,
The moon is old, Qfwfq agreed, pitted with holes, worn out. Rolling naked through the skies, it erodes and loses its flesh like a bone that’s been gnawed. This is not the first time that such a thing has happened. I remember moons that were even older and more battered than this one; I’ve seen loads of these moons, seen them being born and running across the sky and dying out, one punctured by hail from shooting stars, another exploding from all its craters, and yet another oozing drops of topaz-colored sweat that evaporated immediately, then being covered by greenish clouds and reduced to a dried-up, spongy shell.
What happens on the earth when a moon dies is not easy to describe; I’ll try to do it by referring to the last instance I can remember.
