A Habitable Zone, Life Zone, or "Goldilocks Zone" is a planetological term for the area of stellar system space in which the right conditions for conventional sophont life is thought to be most favorable.
- Imperial scientists often use the shorthand abbreviation HZ or Hz to indicate this term.
- Some also call it the green band.
In practice, this zone tends to be a few planets out from the main star of a system, in which the conditions for liquid water, temperate weather, and other necessary conditions for conventional life can arise.
- Too far out, and liquid water no longer exists, meaning that only cryomorphs, or extreme cold species can survive.
- Too far in, and only thermomorphs, or extreme heat-loving species can survive.
- And of course, there are hundreds of other factors also involved.
Orbital Location of the Habitable Zone
- However, in a hypothetical 12 orbit system, orbit 6.5 is considered an ideal HZ under the right conditions. Orbits 6 and 7 are also considered part of the life zone.
The idea of a Habitable Zone was independently developed by many different major and minor race sophont species.
- However, the one thing that most of these Charted Space species hold in common is that they are conventional carbon-based lifeforms. Their idea of habitability differs greatly from exotic or unconventional lifeforms such as Jovionoids.
