Unless you live under a rock you know that 50 years ago today the first artificial satellite, Sputnik 1, was launched by the Soviet Union. That one is not orbiting around anymore, but you can review my analysis of the list of satellites that are currently up there (and Kepler's second law, and geosynchronous orbits), as well as worry about orbiting debris. All of that may make you want to move under a rock for safety.
