• It is a planetological term.

Description (Specifications)

A Garden World or temperate world possesses a safe temperate environment by definition, which does not require protective equipment for humans or other sophonts, who share similar breathable environments (...shirt sleeve worlds). The term is synonymous with garden world in most climatic aspects.

History & Background (Dossier)

A Temperate World is hospitable to most sophonts. Its size, atmosphere, and hydrographics make it an extremely attractive world to conventional lifeforms.

• A Terra-norm isn't as desirable as a Terra-prime world, but it still possess a wide variety of features that allow for easy residence by most sophont species.
• In practical terms, this means a moderate to large world, moderate to high hydrographics, an untainted standard pressure atmosphere, and a standard gravity.
• Most species also prefer a moderate sun in the G2 V to G3 V range.

Traditional Definition of a Inhabitable World

The early Terrans and later Solomani defined a desirable world as a Terra-norm or Terra-prime worlds.

• This later became defined as the following characteristics: Atm 4-9, Hyd 4-8.
