System Data

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

• The mainworld.
• x7 secondary rocky worlds.
• x2 planetoid belts.
• x3 gas giants.

Mainworld Data

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's colder outer H- region.
• It receives relatively low levels of stellar energy.

Mainworld Size (S)

Iroca 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)

Iroca has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. This atmosphere also contains an unusual taint such as disease, a hazardous gas mix, pollutants, or sulfur compounds, which requires the use of a Filter Respirator Combination Mask. Some taints may require more protective equipment. TL–5 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Iroca has 25-35% of its surface covered by liquid water. It has a few small seas. Wilderness refueling is possible. Water for the inhabitants will be recycled.

• The world experiences low temperatures.
• Much of the surface is covered in glaciers, ice, frost, and snow.

Satellites:

The world does not retain any natural satellites.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.
