Analysis of the orbit lifetime of CubeSats in low Earth orbits including periodic variation in drag due to attitude motion
It is estimated that more than 22,300 human-made objects are in orbit around the Earth, with
a total mass above 8,400,000 kg. Around 89% of these objects are non-operational and
without control, which makes them to be considered orbital debris. These numbers consider
only objects with dimensions larger than 10 cm. Besides those numbers, there are also
about 2000 operational satellites in orbit nowadays. The space debris represents a hazard
to operational satellites and to the space operations. A major concern is that this number is …
