The International Space Station is planning to change its orbit after narrowly avoiding two pieces of space junk.

A broken Russian satellite and the remains of an Indian rocket passed within miles of the ISS last week.

Russian space program's Mission Control say the ISS may be moved into a different orbit to lower the risk of a possible collision with any of the 21,000 pieces of debris orbiting the Earth.

Booster rockets would be used to change the course of the space station where there are currently six astronauts on board.
