Ours is a lonely moon. No one likes it, and no one’s like it.

The product of a brief and fateful union between the earth and “a body as big as Mars” in the back alley of the solar system, our moon has never quite come to grips with its lack of a present father figure With a distant mother and no siblings, the Moon has no true peers to turn to, and has always had to reassure itself that, someday, definitely someday, it would find a moon just like it, a friend and comrade that it could finally relate to.

Unfortunately, the social workers of the galaxy, astronomers, have recently had to bear the bleak news to the Moon that it is, at best, an ”uncommon moon”, and that the chances of it ever finding its soul mate are “pretty sucky.”

Most moons were either formed simultaneously to the formation of their planets, or were trapped by a planet’s gravity at some point. Our moon was probably created thirty to fifty million years after the formation of the solar system by a massive impact between Earth and a Mars-sized body (the impact would have tossed enough material into “circumterrestrial orbit” to form the Moon). These sort of moon-creating knock-ups, if you will, leave a cloud of telltale dust in a star system, allowing scientists a general idea of which moons were created that way. By examining how many star systems have this dust could, astronomers have determined that it is likely that only 5 to 10 percent of moons (at most) share a similar origin to ours.

This was an understandably crushing revelation for the Moon. It remains in a gray mood, despite the consolations of people around the world, many of who have insisted that it is “still pretty.”
