=== Orbital Zones ===

 

==== Habitable Zone ====

The [[habitable zone]] (the '''H''' zone) is the orbital position around a star where the energy from that star falling on a hypothetical [[Terra (world)|Terra]]-like world would produce moderate temperatures and allow liquid water to exist. These conditions are the most likely to allow life, both native or introduced, to survive without artificial assistance. Smaller, less energetic stars may not have a [[habitable zone]]. Not all worlds that orbit within a [[habitable zone]] are habitable, or even hospitable.

 

==== Inner System ====

The region within a system located [[starward]] of the [[habitable zone]]. It is generally too hot to allow liquid water, breathable atmospheres or advanced forms of life. Smaller, less energetic stars may not have an inner system.

 

==== Outer System ====

The region within a system lying spaceward of the [[habitable zone]]. It is generally too cold to allow liquid water, breathable atmospheres or advanced forms of life. Local conditions and circumstances may dramatically affect this, however. The mechanics of star system formation mean that gas giants are more likely to occur within the outer system. Smaller, less energetic stars may only have an outer system.

 

==== Water Worlds ====

[[Ocean-covered world]]s with temperate climates are more likely within the '''H–''' position, largely to do with the way that such worlds cycle stellar energy. Ocean-covered worlds occuring within the '''H''' and '''H+''' zones are generally far colder than their orbital distance would suggest and often have extensive icecaps.

 

=== Empty Orbits ===

Some systems may not have worlds filling every available near-bodean orbital position. In such cases, these are defined as empty orbits and are noted as such. An example of this occurs in the Sol system, with orbital position (I) (lying 0.2 [[AU]] from the star, inside of Mercury's orbit) being defined as empty.

 

=== Shared Orbits ===

Some systems may have multiple worlds sharing the same near-bodean orbital position. In such cases, an additional orbital position is denoted within the bracketed orbital position, separated by a hyphen.

=== Notes ===

This system of describing star systems, while broadly used within the [[Distant Fringe]], is not utilised elsewhere.

==== Very Large Stars ====

Some stars are large enough to encompass inner orbital positions, rendering those orbital positions unavailable due to them being physically within the star. In such circumstances the orbital position at which the star's corona lies is defined and unavailable orbital positions are noted. The scorched metallic cores of dense worlds, remnants from an earlier stage of the system's evolution, may continue to orbit deep within the hot gaseous body of the star.

 

==== Companion Stars ====

The presence of one or more companion stars orbiting the primary may render certain orbital positions unavailable. This is noted in the system description.

=== Gas Giants ===

 

==== Hot Gas Giants ====

Occasionally, celestial mechanics and gravitational forces (most probably due to the interactions of multiple large planetary bodies during the evolution of the system, or perhaps disruption generated by the passing of a wandering star) may cause gas giant worlds to migrate inward through the star system. Some, rather than burning up in the star's photosphere or being slung out of the system, instead settle into a stable orbital position close to the star.
