As you probably know, the Earth has only one natural orbiting body, the moon. However, you may not know that the Earth has several co-orbiting bodies - objects, most asteroids, which share the orbit of the Earth with the Earth and sometimes even enter into orbit around the Earth for periods of time. I could not find a nice comprehensive list on the internet, so here is my go at it. You can search deeper for more detailed explanation of each body.
