Space Junk

Thousands of nuts, bolts, gloves and other debris from space missions form an orbiting garbage dump around Earth, presenting a hazard to spacecraft. Some of the bits and pieces scream along at 17,500 mph.
The oldest debris still on orbit is the second US satellite, the Vanguard I, launched on 1958, March, the 17th, which worked only for 6 years.
In 1965, during the first american space walk, the Gemini 4 astronaut Edward White, lost a glove. For a month, the glove stayed on orbit with a speed of 28,000 km / h, becoming the most dangerous garment in history.
More than 200 objects, most of them rubbish bags, were released by the Mir space station during its first 10 years of operation.
The most space debris created by a spacecraft's destruction was due to the upper stage of a Pegasus rocket launched in 1994. Its explosion in 1996 generated a cloud of some 300,000 fragments bigger than 4 mm and 700 among them were big enough to be catalogued. This explosion alone doubled the Hubble Space Telescope collision risk.
