Terant 340 has both a thin tainted atmosphere and no surface water which makes habitation by sophonts difficult. The system has a population between 10,000 and a million, lacking the industrial base to be completely self-supporting. It is a member of Darrian Confederation in the Darrian Subsector of Spinward Marches Sector. 100% of the world's population is the Minor Human Race Daryen.

• Terant 340 is a member of the Spinward Main.

Description (Astrography & Planetology)

Stellar Data

Terant 340 is a binary star system.

System Data

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

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

Terant's primaries have many interesting anomalies which intrigued the Darrian astrophysicists. The planetoid belts harbor enough resources to make self-sufficiency possible. Terant 340 is the largest chunk of circling debris prevented from coalescing into a planet by the disturbing influence of the dwarf companion and three gas giants. The system has no other worlds between gas giant and planetoid size.

Mainworld Data

Terant 340 orbits within its star's habitable zone.

• It receives moderate levels of stellar energy.

Mainworld Size (S)

Terant 340 is a Meso World between 7,200km and 8,800km in diameter. The world has a standard gravity between 0.4G and 0.57G. The horizon will appear about 4km away.

Mainworld Atmosphere (A)

Terant 340 has a pressure of 0.43 to 0.70 atmospheres. While the thin atmosphere does not require survival gear 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 Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Terant 340 has no free-standing water or ice on the surface. Wilderness refueling isn't possible on this world. Water for the inhabitants needs to be imported and extensively recycled. These worlds are classified Desert World or a Hell World depending on their atmosphere.

Mainworld Geography and Topography

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

(Blank map, predominantly dry world.)

History & Background (Dossier)

A desert world, Terant 340 was colonized under domes using strict water recycling.

World Starport (Sp)

Terant 340 has a Class D Starport, a poor quality installation which has few of the expected amenities. There is unrefined fuel for starships and a limited variety of ship provisions. There is no shipyard of any kind, but there may be parts and technical support for doing minor services and repair. Ports of this classification generally consist of only a downport, unless this is a trade port or system with an hostile environment mainworld.
