Does the Earth have another moon?
I was just wondering what are the chances that there is a small object (say less than 1 km but more than few meters) that orbits the Earth but has remained undetected by us? Are we actually scanning the space around the Earth continuously for orbiting bodies?
You mean _besides_ the $10,000$ or so artificial bodies of about that size already there?
Not strictly satellites/moons, but certainly companions are 2010 TK7 with a diameter of ~300 m, an Earth trojan at the L4 point, and the ~5 km 3753 Cruithne in a peculiar orbit locked to the Earth's.

The earth is a moon of the moon, so technically, yes, there are two moons ~
