In 1956, there was no manmade junk in orbit around Earth. The launches of Sputnik 1 in 1957 and Explorer 1 in 1958 changed that. And every launch that has reached orbit since then has left behind some bits of junk. Stuart Grey of University College London has created an animation of the accumulation of all of the tracked space debris, which now nearly reaches 20 000 pieces.
