Metellus (Ca 2811) is an icy, non-agricultural and nonindustrial vacuum world, whose surface is ice-capped and with nearly all of its water frozen and warranting hazardous environment precautions.

  • It is unable to produce quality foodstuffs and must import them.
  • It requires extensive imports of outside technology to maintain a modern, star-faring society.
  • This is a frozen world, with a climate of extremely low temperatures.
  • 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.
  • It is a member of the Solomani Confederation in the Zarn Subsector of Canopus Sector.
  • This world-system has a Naval Base, usually associated with military starships, which may be located on or off-world.

Description (Astrography & Planetology)

Notes

The two stars of the Metellus system have an average separation of 18.5 AU and orbit a barycenter that lies between them.

System Data

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

  • The mainworld, orbiting the primary star.
  • x11 secondary rocky worlds. Five orbit the primary star, six orbit the secondary star.

Mainworld Data

Metellus 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.

It orbits at the outer edge of its star's habitable zone.[2]

Mainworld Size (S)

Metellus 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)

Metellus 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)

Metellus has 05-15% 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.

History & Background (Dossier)

Comp-Prog-Dav-R-Deitrick-Starter-Trav-Page-16 16-July-2018a.jpg

Metellus is a member of (and the namesake of) the Metellus Group, a small cluster and minor trade route lying in the coreward-trailing quadrant of Canopus Sector, close to the border with Aldebaran Sector.

Although it lies within the territory of the Confederation, Metellus is not officially a member of that state, choosing instead to remain as a technically neutral world. Despite its neutral status, it relies on the Confederation for trade and defense and actively cooperates with Solomani interests.

Solomani Security keeps a close eye on things to ensure the security of the Confederation and the well-being of its loyal citizens. Almost anyone could be a SolSec informant, passing on all sorts of useful information: some gain a reward or benefit for their actions, others are coerced, but many see it as an act of duty to help protect the Solomani state and its interests.

World Starport (St)

Metellus has a Class C Starport, an average quality installation which features amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.

World Population (P)

Metellus has a population of 2,000,000 sophonts (millions).

  • This is a Nonindustrial World, too small to support the complete chain of production of most goods from start to finish.
  • The population almost entirely consists of Solomani humans.

Linguistic Topography

The most commonly heard languages are:

World Technology Level (T)

Metellus possesses a Technology Level of TL–7.

  • Common Communication technologies for this TL include: Early video and early satellite communication networks.
  • Common Power Generation technologies for this TL include: Early fuel cells, solar energy, and geothermal power sources.
  • Common Transportation technologies for this TL include:
    • Land: Improved automobiles, hovercraft, and bullet trains.
    • Water: Hydrofoils and early triphibians.
    • Air: Hang gliders and supersonic jets.
    • Space: Deep space probes and interplanetary spacecraft (System Craft).

World Government (G)

Metellus is governed by a Representative Democracy where government leadership is by representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referenda, votes by eligible voters on specific subjects.

World Law (L)

Metellus has a moderate law level with laws covering many areas of government and interaction. These laws are simple enough that most people can act as their own advocate, though for serious issues a professional is recommended. Law enforcement officials will be present, but not in great numbers. Light assault weapons, and anything more destructive, are typically regulated or prohibited.
