Terran Prime, Terran Norm

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.
