This guy I work with is under the impression that it must be difficult to keep satellites from running into each other. That they are constantly brushing by each other. My arguement was to say pretend the number of satellites was the total number of cars in the world. how often would you expect those cars to run into each other. they would be lucky to even see another car. I'm just curious as to how many satellites are actually up there and what percentage are in a geosync. orbit. and finally is it possible to orbit in a plane that doesn't bissect the Earth evenly?
