170000000 Pieces of Space Junk
April 28, 2013 | Sixth European Conference on Space Debris

“Since 1957, more than 4,900 space launches have led to an on-orbit population today of more than 22,000 trackable objects, with sizes larger than 10 cm. Approximately 1,000 of these are operational spacecraft. The remaining 94% are space debris, i.e. objects which no longer serve any useful purpose. [...] In addition, an estimated 700,000 objects larger than 1 cm and 170 million objects larger than 1 mm are expected to be in Earth orbits.” Quoted from the ESA Conference on Space Debris.
