Graveyard orbit

A graveyard orbit, also called a junk orbit or disposal orbit, is an orbit that lies significantly away from common operational orbits, where spacecraft are intentionally placed at the end of their operational life. Most commonly, it refers to a supersynchronous orbit that lies significantly above synchronous orbit. It is a measure performed in order to reduce the probability of collisions with operational spacecraft and of the generation of additional space debris (known as Kessler syndrome). After moving a spacecraft to a graveyard orbit, it will typically be passivated.
