Jump map from Travellermap.com

Theta Tauri is an icy, barren vacuum world, with no overt population, government, or law level, which would warrant hazardous environment precautions if anyone lived here.

• 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 a member of the Solomani Confederation in the Narmada Subsector of Aldebaran 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.
• x9 secondary rocky worlds.
• x2 planetoid belts.
• x2 gas giants.

Mainworld Data

Theta Tauri is tidally locked to its primary star.

• The star is always high in the sky on the bright face, it hangs on horizon in the twilight zone, while the cold dark face is in permanent darkness.
• The world experiences libration - a regular wobble - as it orbits, causing the star to move in the sky.

Mainworld Size (S)

Theta Tauri 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)

Theta Tauri has a pressure of less than 0.001 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)

Theta Tauri 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 thick layers of regolith and dust of meteoric origin, leaving only a part of the icy outer shell exposed.
• Below the outer icy shell there may be a world-ocean of liquid water.

Mainworld Geography and Topography

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

The surface of the world is heavily cratered. Substantial ice sheets cover its dark face.
