System Data[edit]

Benner System[edit]

The primary is Benner, an ordinary white main sequence star. It has a luminosity of 11.26 Sols, a mass of 1.86 Sols, and a diameter of 2.421 million km. The inner system consists of (II) a hot small gas giant, and (V) an exotic atmosphere bigworld – orbital positions (I), (III) and (IV) are empty. (VI) a corrosive atmosphere inferno world orbits within the habitable zone. (VII) a ringed large gas giant, and (VIII) a small ice giant form the outer system. The outer worlds retain satellites.

Orgon-Cephet Subsystem[edit]

The companion is Orgon, a yellow subdwarf star lying approximately 2,200 AU from Benner. It has a luminosity of 0.213 Sols, a mass of 0.542 Sols, and a diameter of 896,000 km. The inner system consists of (I) a corrosive atmosphere inferno world. (II) Cephet orbits within the habitable zone and is designated the mainworld. (III) an exotic atmosphere bigworld, and (IV) a small gas giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(II) Cephet[edit]

(II) Cephet is designated the mainworld. It orbits Orgon at a mean distance of 0.38 AU (56.8 million km), within the habitable zone. It has an orbital period of 116 days 5 hours: it is tidally locked to [primary]. The axial tilt is 4 degrees. Cephet has a diameter of 9,985 km, a density of 5.78 g/cm³, and a surface gravity of 0.82 G. The world is geologically very active. Its atmosphere is rated as Exotic, with a mean surface pressure of 12.4 bar and a composition of 95% nitrogen (N2), 3% carbon dioxide (CO2), 1% nitrogen dioxide (NO2), sulfur dioxide (SO2) and carbon monoxide (CO), and 1% argon (Ar), water vapor (H2O), methane (CH4), neon (Ne), abiotic oxygen (O2), and other trace gases. The world has no hydrosphere. Mean surface temperature: -43°C. The climate is rated as Very Cold and is static, with no seasonal changes during the local year. The atmosphere is very active and powerful weather systems driven by the star scour the globe.

Mainworld Geography and Topography[edit]

Total surface area: 313 million km².

World starport[edit]

Cephet has a poor quality starport.

  • A Class-D Starport Facility has minimal if any shipyards and can only perform extremely limited repair work.
  • This facility has many skilled personnel who can perform minor repair work.
  • This facility has refueling infrastructure and limited refining capabilities. One may purchase unrefined fuel here.
  • Starports of this class very rarely have both a Lowport and a Highport.

World technology level[edit]

Cephet possesses a Technology Level of TL–9.

  • Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
  • Common Power Generation technologies for this TL include: Early fusion power.
  • Common Transportation technologies for this TL include:
    • Land: Ultra high-speed trains and early grav vehicles.
    • Water: High efficiency sailcraft, multihulled seacraft, improved artificial gears.
    • Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
    • Space: SSTO spacecraft, early military spacecraft, and interstellar STL starships
    • FTL: Prototype Jump Drive-1.

World government[edit]

Cephet has no well-defined government structure.

  • In many cases, tribal, clan or family bonds predominate.
  • The typical power source of this government is an Pantocracy or Chaos.
  • The typical power structure of this government is a Confederation (Anarchy).
