content: You mean a Lagrangian Point? Also, orbital decay can take decades or more depending on the altitude, as orbital decay is based on atmospheric drag. In Low Earth Orbit, this can happen in a matter of months. Higher up, and you're talking years. Geostationary and geosynchronous satellites are high up enough that they won't re-enter for centuries (if ever), and only require slight adjustments from time to time. The space station, on the other hand, gets regular boosts every now and then. It's higher than a lot of other objects in LEO, but it also has those massive solar panels causing drag.
