====== System ======

A star system, also known as a planetary system or simply a system, is a group of bodies orbiting a [[stars|star]]. Star systems usually consist of one or more [[planets|planets]] or [[gas giants|gas giants]] in orbit around a single or binary star. Debris from the formation of the system is still around in the form of [[asteroid belt|asteroid belts]], [[trojan asteroids|trojan asteroids]] and [[rings]].

The star system forms the basis of the [[economics]] rules. This is because transfer of goods between worlds in a star system is free due to the prevalence of space travel.

A star system takes up (7|2) [[sector capacity]].

Rules for the design of star systems can be found in [[system creation]]. Advanced options related to systems include the establishment of a [[settlement]].


===== Shared System =====
It is possible to share a system between multiple factions. This situation can be created through, for example, starting a [[Settlement#Shared Settlement]], or through transfering control of a world to another faction.

It is only possible to share control at the level of whole worlds, that is, any world in a shared systems is as a whole under the control of a single faction.

Sharing worlds in a system impacts several aspects of the game:

  * A shared system does not grant [[Sovereignty]].
  * System-wide projects can be veto'd by any party that controls a world in the system. To build a project, the builder must satisfy all requirements, and the builder must pay the full upkeep. Regardless of who pays upkeep or built the project, system-wide benefits are granted system-wide.
  * [[Population]] is controlled by a single faction, and resides and grants bonuses on worlds of that faction. System wide benefits from population apply as usual, with the faction to which the population belongs having the final say on any choices regarding these benefits.
  * It is possible to [[trade]] goods between factions in the same system, doing so does not require a Trade Fleet.
