Colonizable Planets

Normal planets can support, though their efficiency at doing so depends on their , , and as well as how closely their  and  match the preferences of your Empire.

Planet Type
range from frozen balls of ice to molten infernos and everything in between. None are bad in themselves, but each Empire will have one type that is ideal, some types that are tolerable, and some that are hostile, with penalties to, , and depending on how far removed they are from your Empire's ideal type. Planet Types other than ideal require the appropriate, and can be changed by with the appropriate  technology. The negative effects of a hostile environment can be offset for a small portion of the population with a.

Planet Size
The of planet determines both its  and. Both will place fundamental limits on eventual maximum benefit of the as all colony  are multiplied by  and  determines not only the maximum number of  a colony can support, but also provides bonuses, some of which are Empire wide. Perhaps the most important factor of a planet as it cannot be changed by any means and places a fundamental limit on the effectiveness of the colony.

Mineral Richness
The of a planet provides a  bonus to, ranging from 1 for ultra-poor to 8 for ultra-rich. Richness can only be changed by special events.

Ecological Level
The of a planet provides bonuses to  and  Growth at a rate of 10% per level. It ranges from 0--decidedly unpleasant--to 3, a virtual Garden of Eden. With the proper technlogy it can be raised through.

Planetary Gravity
The of a planet can be low, medium, or high. Each Empire has a preference and suffers penalties to and  depending on how far the gravity is from their preference. A can protect a small portion of the population from these negative effects, while a  or a  can alter the gravity of the entire planet, though both require.

Planet Construction
Searching the galaxy for habitable planets and taking what you can find is one thing. Constructing ideal planets yourself is another. One option when you discover is the  tech. Take it. With just 3 resources, it allows you to construct ideal, rich to ultra-rich, high ecological level planets from  and Barren Worlds in any  you have colonized.
