{{Disambig}}
A [[Satellite]] is a natural or an artificial body in orbit around a [[world]].
 
* A [[Satellite World]] is a satellite that has taken on socioeconomic importance, usually as a [[mainworld]].
 
* They are commonly known as [[moon]]s to many.
 
  
== Description ([[Specifications]]) ==
+
There are multiple [[AAB]] [[Library Data]] articles with the name '''Satellite'''.  
=== Artificial Satellites ===
+
* Use the following list to determine the exact article:
An artifical satellite is typically a device, a structure or more rarely a small body such as a planetoid placed in orbit around a [[world]] in order to act as a platform or a base, to collect information or to relay or send communications.
+
* Debris or wreckage may orbit a [[world]] and be classified as an artificial satellite.

=== Natural Satellites ===
 
A natural satellite, often called a moon, is an astronomical body that orbits a [[world]]. Satellites always have a lower mass than their parent world and usually have a smaller diameter.
 
* In rare cases a world with a small diameter and a high mass may retain a satellite with a larger diameter but a lower mass.
 
* Worlds and satellites with similar masses and diameters may be referred to as binary planets or [[Double World]]s.
 
 
 
A satellite and its parent world orbit a barycenter, their center of mass: this is the point around which they both orbit.
 
* If the parent world has substantially more mass than its satellite, the barycenter will be located within the parent world (such as [[Terra (SR 1827) (world)|Terra and Luna]] in the [[Sol (star)|Sol]] system).
 
* If the masses of the two bodies are more equal, the barycenter will lie at some point along the line of their mean separation (such as [[Pluto (world)#Charon|Pluto and Charon]] in the [[Sol (star)|Sol]] system).
 
 
 
== History & Background ([[Dossier]]) ==
 
==== Numbers and Positions ====
 
Satellites are classified as ''major'' (created as part of the star system generation sequence) or ''minor'' (...almost always very small bodies captured by the parent world, and considered too small or insignificant to have their own separate details within the system description).
 
* [[World]]s lying within the inner system have a maximum of 1 major satellite.
 
* [[World]]s lying within the [[habitable zone]] have a maximum of 2 major satellites.
 
* [[World]]s lying within the outer system have a maximum of 3 major satellites.
 
* [[Gas giant]]s have a maximum of 5 major satellites. They generally have many additional minor satellites.
 
 
 
A satellite's orbital distance from its parent world is measured in multiples of the parent world's diameter.
 
* Natural satellites orbiting within 70 diameters of their parent world are [[tidally locked]] to that world. Tidally locked satellites do not generally have [[twilight zone]]s.
 
* Satellites orbiting their parent world at 70 diameters or more have their own rotation period.
 
 
 
Satellite orbits are identified by alphabetic letters in the following sequence:
 
: Ay-Bee-Cee-Dee-Ee-Eff-Gee-Aitch-Eye-Jay-Kay-Ell-Em-En-Oh-Pee-Que-Arr-Ess-Tee-Yu-Vee-Dub-Ex-Wye-Zee.
 
 
 
==== Naming Conventions ====
 
Satellites may be individually named (such as [[Terra (SR 1827) (world)|Terra's]] satellite [[Luna (world)|Luna]]), or they may simply be given a designation.
 
 
 
== [[World]]s & [[Sector]]s ([[Astrography]]) ==
 
[[Satellite World]]s are primarily found in the following areas:
 
* [[Charted Space]]
 
 
 
=== World Listing: 1105 ===
