      Hi Zak,
      Currently there are approximately 2,500 artificial satellites orbiting the Earth. They don’t all orbit at the same distance out from the Earth, but some regions are popular (e.g. a radius that means they rotate at the same speed as Earth, and so stay above the same place all the time). It’s getting quite crowded out there! Take a look at this image, each point represents a satellite or piece of ‘space junk’.
