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 ...
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 ...
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.
Not to be confused with Graveyard orbit. The spacecraft cemetery, known more formally as the South Pacific Ocean (ic) Uninhabited Area, [ 1 ][ 2 ] is a region in the southern Pacific Ocean east of New Zealand, [ 3 ] where spacecraft that have reached the end of their usefulness are routinely crashed. The area is roughly centered on " Point Nemo ...
The satellites are pinpoint, while stars have created star trails due to Earth's rotation. A geostationary orbit, also referred to as a geosynchronous equatorial orbit[ a ] (GEO), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km (26,199 mi) in radius from Earth's center, and following the ...

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.
Very low Earth orbit. Very low Earth orbit is a range of orbital altitudes below 400 km (250 mi), and is of increasing commercial importance in a variety of scenarios and for multiple applications, in both private and government satellite operations. Applications include earth observation, radar, infrared, weather, telecommunications, and rural ...
