Bethurm is an icy, low-population vacuum world, with a population less than 10,000 sophonts in population size, warranting hazardous environment precautions.

System Data[edit]

Sanadin-Bethurm System[edit]

The primary is Sanadin, an ordinary red main sequence star. It has a luminosity of 0.0268 Sols, a mass of 0.4258 Sols, and a diameter of 658,000 km. (I) Manaqua, an exotic atmosphere stormworld, orbits within the habitable zone: (Ia) Bethurm is its largest satellite and is designated the mainworld. (II) a dense stony planetoid belt, (III) a small gas giant, (IV) a ringed small ice giant, (V) an exotic atmosphere bigworld, (VI) a trace atmosphere iceworld, and (VII) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Pequan Subsystem[edit]

The companion is Pequan, a dim red subdwarf star lying approximately 1150 AU from Sanadin. It has a luminosity of 0.0056 Sols, a mass of 0.124 Sols, and a diameter of 229,000 km. (I) a trace atmosphere iceworld, (II) a sparse icy planetoid belt, (III) a small gas giant, and (IV) a vacuum iceworld form the outer system. Only the gas giant retains satellites.

(I) Manaqua[edit]

(I) Manaqua orbits Sanadin at a mean distance of 0.23 AU (34.4 million km), within the habitable zone. It has an orbital period of 61 days 18 hours and a rotation period of 33 hours. The axial tilt is 90 degrees: the northern pole points directly towards the star. Manaqua has a diameter of 6,625 km, a density of 4.75 g/cm³, and a surface gravity of 0.45 G. Its atmosphere is rated as Exotic, with a mean surface pressure of 1.43 bar and a composition of 81% nitrogen, 17% carbon dioxide, 1% argon, and 1% water vapour, ammonia, methane and other trace gases. The world has no hydrographics. Mean surface temperature: 43°C. The atmosphere is violent and powerful weather systems, driven by the star, scour the globe. The climate is static.

Mainworld Data[edit]

(Ia) Bethurm[edit]

(Ia) Bethurm is the only moon of (I) Manaqua and is designated the mainworld. It orbits its parent world at a mean distance of 13 diameters (86,000 km), with an orbital period of 4 days 4 hours: it is tidally locked to Manaqua. It has an axial tilt of 3 degrees. Bethurm has a diameter of 3,074 km, a density of 4.33 g/cm³ and a surface gravity of 0.19 G. Tidal stresses caused by the gravitational pull of Manaqua and of the star cause regular geological activity. Its atmosphere is rated as Vacuum. Around 16% of the surface is covered in deposits of water-ice. Mean surface temperature: -25°C.

Mainworld geography and topography[edit]

Total surface area: 30 million km², Land surface area: 25 million km², Ice surface area: 5 million km².

Native lifeforms[edit]

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

History & Background (Dossier)[edit]

World starport[edit]

Bethurm has a routine quality starport.

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

World technology level[edit]

Bethurm possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.

World government[edit]

Bethurm has a Self-Perpetuating Oligarchy government.

  • It is a government by a restricted minority, with little or no input from the masses.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.
