what is space debris
Space debris, also known as orbital debris, space junk and space waste, is the collection of manmade defunct objects in orbit around Earth. This includes spent rocket stages, old satellites and fragments from disintegration, erosion and collisions.anmade space debris has been dropping out of orbit at an average rate of about one object per day for the past 50 years. Variation in the average rate occurs as a result of the 11-year solar cycle, averaging almost three objects per day at solar maximum due to the heating (and expansion) of the Earth's atmosphere.
