Jump map from Travellermap.com

Porfiron is an icy, barren world, with no overt population, government, or law level.

• Its surface is ice-capped with little or no atmosphere and nearly all of its water frozen.
• This world could be populated by a determined group if they had an inclination to do so...
• It is an unclaimed Non-Aligned world located in the Ronodik Subsector of Theron Sector.

• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.

System Data

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

• The mainworld.
• x4 secondary rocky worlds.
• x1 planetoid belt.
• x4 gas giants.

Mainworld Data

Porfiron is a Twilight Zone World.

• In the narrow region between permanent night and permanent day, the two stars eternally hang on the horizon.

The mainworld orbits within the two stars' combined Habitable Zone.

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

Mainworld Size (S)

Porfiron is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

Mainworld Atmosphere (A)

Porfiron 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)

Porfiron has 25-35% 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 30% 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.
