What is space waste and how to reduce it

Space debris (also known as space pollution, space waste, space trash, or space garbage) is defunct artificial objects in space—principally in Earth orbit which no longer serve a useful function.

There are four techniques that can move debris from heavily trafficked orbits: (1) deorbiting (the deliberate, forced reentry of a space object into the Earth's atmosphere by application of a force, usually via a propulsion system) at EOL; (2) orbital lifetime reduction

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
