Terran Prime and Terran Norm are classification terms given to worlds with certain desirable physical characteristics.
Terran Prime (T-prime) worlds are worlds similar to the Terran standard type; such worlds are highly prized as habitations. To be classed as Terran Prime, a world's physical characteristics must fall within the following ranges:
|Size||6 - 9|
|Atmosphere||4 - 9|
|Hydrography||3 - 9|
|Gravity||0.6 - 1.1G|
Within this category is the Terran Norm (T-norm) type:
|Size||7 - 9|
|Atmosphere||6 - 7|
|Hydrography||5 - 7|
|Gravity||0.75 - 1.1G|
This latter classification almost guarantees successful colonisation or tourist industries.
Note that the actual UPP of Terra ( Sol / Solomani Rim 1827) is A-867A69-F.
