Well, they're man-made, but I think all the socks I've lost in the dryer are up there somewhere.

No. However, it has been theorized that at various times in the past, the Earth may have captured small asteroids that could have orbited as moons for relatively short periods of time before their orbits destabilized. Also, there is an asteroid, Cruithne, that has a resonance with Earth, and when observed from Earth appears to orbit it in a horseshoe shape. In actuality, it orbits the sun, but approaches Earth at specific points in its orbit. In addition, there are dense dust clouds that share the moon's orbit, sixty degrees in front of and behind it.

No....not to my best knowledge. :)
Which is a weird one when you consider that with the Moon's orbit, you naturally get five Lagrange points, and at least three of them *are* stable enough that if anything moved slowly enough *into* them, they could come to a relative halt and be stuck there, where all the gravity from the Earth/Moon/Sun trio averages out.
I mean we do have a LOT of debris and junk naturally floating around, lots of dust and asteroids, so why DO we only have one moon when almost every planet in the system that *has* moons has at least two?
I am not sure I get that, just in terms of the physics. Maybe the point of view is skewed incorrectly with regards to the system's relative lack of external gravity, but the whole thing seems wobbly, unbalanced to me....
And well, two of those five Lagrange points are unstable, and the earth *does* wobble on its own axis of rotation....
Oh well, live and learn I guess. **shrugs**

Nope, although some people have thought so in the past. There are some asteroids that share Earth's orbit around the Sun, but they don't actually orbit Earth, so they aren't moons of Earth. Be very skeptical if you find any info on the web that says otherwise. Check the link below for more info on any asteroid:

There is some debris orbiting in the Lagrange points in the orbit of the moon.
