Worlds in this universe are grouped inside systems, which are scattered around several galaxies in the Universe. You can create a colony on any of them, however most are too unsuitable for the colony to prosper, or even survive.


Planets classification are derived from several of their properties. You must explore them to get detailed information, however, with practice habitability can already be gauged from observation.

Terrestrial, Oceanic, Tundral, Ice, Geothermal, Barren, Desert, Mountainous, Metallic, Gaseous

A planet's class also conveys some information about the resources you can expect to find.

The habitability of a world will affect happiness and health of its inhabitants, in in proxy all other colony parameters. Habitability is determined from a planet's atmosphere, weather, gravity, and temperature. It is an approximation, with each of these having different impacts in detail.

Your people are human, so they prefer planets with 10m/s² gravitational acceleration.

Lower than this will inhibit the development of muscle and bone tissue requiring your every recreation center to provide weight training facilities, and causing hospitals to be overbooked with patients seeking treatment for the minor ailments of low-grav existence.

While slightly higher that 10m/s might only be as bad as low-grav conditions, gravity upwards of 20m/s can wreak havoc on the human body, causing your colonists to collapse from ten minutes of work, and causing the average lifespan to drop to twenty five years of age. Needless to say, only the cruel or desperate colonize extremely high-grav planets. (However, those high-grav planets often have the best resources, so many players choose to colonize just one high-grav planet to obtain the resources they need).

A planet's atmosphere affects colonist happiness and health as well as the planet's habitability. There are five types of atmospheres, from best to worst: oxygen, carbon dioxide, none, hydrogen and acidic.

Temperature is another factor in a planet's habitability, the closer to 15 degrees Celsius the better. Living on a giant ice ball gets old really quickly, and it is hard to get around when your skin spontaneously combusts in direct sunlight.

Each planet has its own levels of abundance of resources. Planets with high levels of resources make excellent colonies to mine on, but the density of the ores causes these planets to have higher gravity.

People tend to name planets that they like, or that are popular. There is nothing wrong with finding a planet out in space that you like and naming it after yourself. There is also nothing wrong with naming a planet to taunt your enemies. The money goes to help the game, and it is easier (and more fun) to refer to "Thunderstorm's Private Island" than "Alpha-A-Whatever #".

(Editors note: Nothing weird happens at Thunderstorm's Private Island, there isn't even an airport.)
