Space debris, Why can´t we see it?
There are around 2275 satellites orbiting Earth of the side of a trailer, so there is no way to see them. The same happens with debris, there are more than 200 million objetcs of the size of an inch around the Globe, but with that size and no light, the human eye can´t see it, but only because you can´t see a threat, it does not mean there is no one.
