System Data

The worlds of the system have been remotely surveyed. They consist of:

• The mainworld.
• x4 secondary rocky worlds.
• x2 planetoid belts.

Mainworld Data

Limited data is available about the body nominated as the mainworld. All of the data has been gathered over centuries of remote observation.

Mainworld Size (S)

This world is a Meso World between 8,800km and 10,400km in diameter. The world has a standard gravity between 0.6G and 0.8G. The horizon will appear about 4.4km away.

Mainworld Atmosphere (A)

This world has a pressure of 1.50 to 2.49 atmospheres. While a Dense Atmosphere requires no survival gear this atmosphere also contains an unusual taint such as such as disease, a hazardous gas mix, pollutants, or sulfur compounds which requires the use of a Filter Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

This world has 95-100% of its surface covered by liquid water with only a few islands and archipelagos. Wilderness refueling is possible. Such worlds are Water Worlds or Ocean Worlds.
