How many pieces of space junk are in space?

Of the 9,600 space objects being tracked, 93 percent of these are space junk. This only includes objects that are larger than about 3 inches in diameter. Smaller objects cannot be tracked. As mentioned above, they are huge in number yet a single fleck of paint has the ability to destroy an astronaut or spacecraft if it hits it, due to the high speed they are traveling. So far, no serious collisions have occurred but a shuttle has had a window damaged by a small particle and a spacewalking astronaut had something similar hit his glove.
