Ras Tennol is a rich desert world with no free-standing water.

  • This world-system hosts a Military Base, usually associated with military ground forces, which may be located on or off-world.

Description (Astrography & Planetology)[edit]

This star system is detailed using the Fringian Variant System Description.

System Data[edit]

Ras Tennol consists of two separate binary star systems lying approximately 4,200 AU apart.

Mentaska-Dollen-Ras Tennol System[edit]

The primary is Mentaska, a huge red giant star. It has a luminosity of 1194 Sols, a mass of 6.74 Sols, and a diameter of 179 million km – the corona lies at 0.6 AU, just within orbital position (III). The companion is Dollen, a tiny dwarf star that orbits at a mean separation of 300,000 km. Dollen has a luminosity of 0.00004 Sols, a mass of 0.83 Sols, and a diameter of 12,500 km. The inner system consists of (IV) a trace atmosphere worldlet, (V) a vacuum inner world, (VI) a very thin atmosphere inner world, (VII) a corrosive atmosphere inferno world, and (VIII) an exotic atmosphere radworld – orbital positions (I) and (II) lie within the star and orbital position (III) is empty. (IX) Ras Tennol orbits within the habitable zone and is designated the mainworld. (X) a thin atmosphere hospitable world, (XI) an exotic atmosphere bigworld, (XII) a trace atmosphere iceworld, and (XIII) a sparse icy planetoid belt form the outer system. Many of the worlds retain satellites.

Plaskin Subsystem[edit]

The far companion is Plaskin, an ordinary red main sequence star that lies approximately 4200 AU from Mentaska. It has a luminosity of 0.0136 Sols, a mass of 0.3626 Sols, and a diameter of 551,000 km. (I) a trace atmosphere iceworld, and (II) an exotic atmosphere radworld form the inner part of the outer system. Orbital positions (III) through (VI) are unavailable due to the presence of the companion star. (VII) a large gas giant, (VIII) a vacuum iceworld, and (IX) a dense icy planetoid belt form the outer part of the outer system. Many of the worlds retain satellites.

Phen Subsystem[edit]

The distant companion is Phen, a dwarf star. It has a luminosity of 0.00003 Sols, a mass of 1.11 Sols, and a diameter of 8,500 km. (I) a trace atmosphere iceworld, and (II) a small gas giant form the outer system. The gas giant retains satellites.

  • Plaskin and Phen, the distant companion, orbit one another at a mean separation of 1.13 AU (169 million km) and have an orbital period around their barycenter of 362 days.

Mainworld Data[edit]

(IX) Ras Tannol[edit]

(IX) Ras Tennol is designated the mainworld. It orbits Mentaska at a mean distance of 5.32 AU (796 million km), within the habitable zone. It has an orbital period of 4 years 266 days and a rotation period of 31.5 hours. The axial tilt is 15 degrees. Ras Tennol has a diameter of 8,369 km, a density of 7.45 g/cm³, and a surface gravity of 0.89 G. The world is geologically active. Its atmosphere is rated as Standard, with a mean surface pressure of 0.81 bar and a composition of 77% nitrogen (N2), 22% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), ozone (O3), neon (Ne) and other trace gases. Approximately 2% of the surface is covered in lakes of liquid water: tidal ranges are negligible. Mean surface temperature: 30°C. The atmosphere is active and strong weather systems driven by the star sweep across the globe. The climate is static.

Mainworld Size (S)[edit]

This world is 7,200-8,799 km in diameter.

  • Standard Gravity: 0.40 - 0.57 G.

Mainworld Atmosphere (A)[edit]

This world has a pressure of 0.71 to 1.49 atmospheres.

Mainworld Hydrosphere (H)[edit]

This world has 0% of its surface covered by liquid. It has no readily accessible, free-standing water.

  • Water is in precious, short supply on this world and must often be imported, such as from ice-bearing planetoids if available.
  • Water recycling is an important part of any settlement on this world.
  • It is a Desert World or a Hell World.
  • It is a super arid (anhydrous) environment.


Ras Tennol retains two natural satellites, an ice-capped vacuum worldlet named Kaled and a cratered vacuum worldlet named Morill:

(VIIa) Kaled (UWP F301417-B, orbiting at 15 Diameters/125,000 km)
(VIIb) Morill (UWP F200368-B, orbiting at 55 Diameters/460,000 km)

Mainworld Geography & Topography[edit]

Total surface area: 220 million km², Land surface area: 216 million km², Water surface area: 4 million km². Ras Tannol is a desert world and has practically no standing water on its arrid, parched surface. The northern hemisphere is taken up by the rugged Tannolin Highlands, the equatorial regions are covered by shifting, wind-scoured dune seas and the Grand Neg, while the southern hemisphere is dominated by the Ras, a huge and ancient impact crater surrounded by a vast fractured landscape of canyons and ravines. The only large body of water on the world is the Salvation Sea, a hot and brackish lake located in the deepest part of the Ras.

Native Lifeforms[edit]

Mentaska-Dollen-Ras Tennol System[edit]

Ras Tennol has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find even a minimal trace of water. Their metabolic functions maintain the process of atmospheric renewal. The interior of the Ras and the fractured terrain around it supports an extensive, self-supporting ecosystem made up of accidentally introduced species. Most of the fauna found on the world is small - typically less than 1 kg in weight - and is largely made up of pests, vermin, former pets and stowaways that have escaped from visiting starships.

The cold marginally hospitable world lying in orbital position (X) (within the H+ region of the outer system) has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find even a minimal trace of shelter and warmth. Their metabolic functions maintain the process of atmospheric renewal.

No other world in the system is known to have native life.

Plaskin Subsystem[edit]

No world in the subsystem is known to have native life.

Phen Subsystem[edit]

No world in the subsystem is known to have native life.

World Starport[edit]

Ras Tennol has an excellent quality starport.

  • A Class A Starport Facility has very well developed shipyards and is capable of producing first rate starships.
  • This facility has many very skilled personnel who can perform not only major repair work, but overhaul work as well.
  • This facility has advanced refueling and refining infrastructure. One may purchase practically any kind of refined fuel here.
  • Almost every starport of this class possesses both a Lowport and a Highport. Sometimes multiple ports of each type.
  • Peace footing (government modifier x1.15). Port Capacity: 920,000 dTons

Almost all of the fuel available at Ras Tennol's starport is imported by Gas Traders from the Plaskin subsystem. Ships registered at the port benefit from substantially discounted fuel prices.


Port facilities within the system include:

World Technology Level[edit]

Ras Tennol possesses a Technology Level of TL–12 or TL-C in Hexadecimal Notation.

World Government[edit]

Ras Tennol has an Impersonal Bureaucracy government.

  • It is a government by agencies which are insulated from the governed.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.

The government of Ras Tennol is the Delegation of Ras, headed by the Prime Fugleman and his supporting staff. It is an extensive bureaucracy divided into different offices of state but dominated by the Directorate of Trade and the Chamber of Taxation. Police duties on the world are carried out by hired Security organisations.

World Military[edit]

Ras Tennol is a major Security clearinghouse and an important operational base for StarMerc organisations performing escort duties along the various Star Lanes that meet at the system.

The current freelance military asset appraisal includes the following Ras Tennol Forces.
