According to NASA's Web site, more than 500,000 pieces of "space junk" are tracked as they orbit the Earth. Although most of the orbital debris is relatively small, some 20,000 pieces are larger than a softball, which NASA keeps track of because scientists say it poses a serious threat, especially to the International Space Station.
