> Even the orbits of satellites decay. Near-Earth satellites, yes; the thinnest wisps of the edge of the atmosphere slow them down. Further out, however, in geostationary orbit, satellites are not subject to such forces. They may be disrupted long-term by the gravitational influence of other distant bodies, but I think I'd worry more about the potential impact from micrometeorites.
