System Data

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

• The mainworld.
• x10 secondary rocky worlds.
• x2 planetoid belts.
• x4 gas giants.

Mainworld Data

Tledlnat is a satellite of a gas giant.

600 px.

The mainworld and its gas giant primary orbit within the outer system.

• They receive very low levels of stellar energy.

• The worlds orbit just inside the stars Jump Shadow.

Mainworld Size (S)

Tledlnat is a Small World between 2,400km and 4,000km in diameter. The world has low gravity between 0.1G and 0.17G. The horizon will appear about 2.5km away.

Mainworld Atmosphere (A)

Tledlnat has a pressure of less than 0.1 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Tledlnat has 15-25% of its surface covered by ice, either in vast sheets or contained deep within craters or fractures on the surface. Wilderness refueling is possible. Water for the inhabitants can be got by mining and melting ice.

• The surface of the world is composed of a crust of ice many kilometers thick.
• Much of the surface is cratered and covered in regolith and thick dust of meteoric origin, leaving only around 20% of the icy outer shell exposed.
• Below the outer icy shell is a world-ocean of liquid water.

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.
