A graveyard orbit, also called a junk orbit or disposal orbit, is an orbit that lies away from common operational orbits. One significant graveyard orbit is a supersynchronous orbit well beyond geosynchronous orbit. Some satellites are moved into such orbits at the end of their operational life to reduce the probability of colliding with ...
There are two types of orbits: closed (periodic) orbits, and open (escape) orbits. Circular and elliptical orbits are closed. Parabolic and hyperbolic orbits are open. Radial orbits can be either open or closed. Circular orbit: An orbit that has an eccentricity of 0 and whose path traces a circle.
Space debris (also known as space junk, space pollution, [ 1 ]space waste, space trash, space garbage, or cosmic debris[ 2 ]) are defunct human-made objects in space – principally in Earth orbit – which no longer serve a useful function. These include derelict spacecraft (nonfunctional spacecraft and abandoned launch vehicle stages ...

Medium Earth orbit. Space of Medium Earth orbits (MEO) as pink area, with Earth and the distance of the orbit of the Moon for reference and to scale. A medium Earth orbit (MEO) is an Earth-centered orbit with an altitude above a low Earth orbit (LEO) and below a high Earth orbit (HEO) – between 2,000 and 35,786 km (1,243 and 22,236 mi) above ...
Supersynchronous orbit. A supersynchronous orbit is either an orbit with a period greater than that of a synchronous orbit, or just an orbit whose major axis is larger than that of a synchronous orbit. A synchronous orbit has a period equal to the rotational period of the body which contains the barycenter of the orbit.
Earth's spacecraft cemetery is used as a site for spacecraft that have reached their lifetime limit due to fatigue and must be retired. [16] Larger spacecraft too massive to burn up during re-entry into the Earth's atmosphere are controlled to crash / splash down in Earth's spacecraft cemetery, a location in the ocean remote from inhabited regions.

Shijian-18 was a Chinese communications and technology demonstration satellite developed and launched by the China Academy of Space Technology on 2 July 2017. It was the maiden flight of the DHF-5 satellite bus, which is designed with 16-year lifespan. Shijian-18 carried 18 experiments on board involving communications and space telescopes.
