Irmin 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 an unclaimed Non-Aligned world located in the Irikusk Subsector of Far Home Sector.
Astrography and Planetology
This star system is detailed using the Fringian Variant System Description.
- It lies within the Harmal Deep rift.

System Data
Manus-Irmin System
The primary is Manus, a dim red main sequence star. It has a luminosity of 0.0055 Sols, a mass of 0.302 Sols, and a diameter of 444,000 km. (I) an exotic atmosphere bigworld, and (II) Hilti, an exotic atmosphere radworld: Irmin is its only satellite, form the outer system. Only Hilti retains a satellite.
Ygg Subsystem
The companion is Ygg, a dim red subdwarf star that orbits Manus at a mean distance of 2.92 AU (orbital position (VI), 436.8 million km) and has an orbital period of 9 years 29 days. It has a luminosity of 0.00054 Sols, a mass of 0.07 Sols, and a diameter of 91,500 km. (I) an exotic atmosphere bigworld forms the outer system. The world does not retain satellites.
(II) Hilti
(II) Hilti (UWP Y6A0000-0) is designated a radworld. It orbits Manus at a mean distance of 0.53 AU (79.3 million km), within the outer system. It has an orbital period of 256 days 11 hours and a rotation period of 43 hours. The axial tilt is 14 degrees. Hilti has a diameter of 9,935 km, a density of 6.03 g/cm³, and a surface gravity of 0.85 G. The world is geologically active. Its atmosphere is rated as Exotic, with a mean surface pressure of 2.31 bar and a composition of 91% nitrogen (N2), 7% carbon dioxide (CO2), 1% argon (Ar), and 1% carbon monoxide (CO), methane (CH4), azane (NH3), abiotic oxygen (O2), water vapor (H2O), neon (Ne), radon (Rn) and other trace gases. Radioactive materials within the surface cause relatively high levels of background radiation: emission rates exceed 25 rads per hour. The world has no hydrosphere. Mean surface temperature: -78°C. The climate is rated as Very Cold and experiences minor seasonal changes during the local year. The atmosphere is active and powerful weather systems driven by the star sweep across the globe.
Satellite
Hilti retains a single natural satellite:
- (IIa) Irmin, designated the mainworld, orbiting at 35 Diameters/345,000 km)
Mainworld Data
(IIa) Irmin
(IIa) Irmin is the only major moon of (II) Hliti and is designated the mainworld. It orbits its parent world at a mean distance of 35 diameters (345,000 km), with an orbital period of 24 days 8 hours: it is tidally locked to Hilti. The axial tilt is 3 degrees relative to Hilti. Irmin has a diameter of 957 km, a density of 4.65 g/cm³ and a surface gravity of 0.06 G. Tidal stresses generated by the gravitational pull of Hliti cause occasional geological activity. The atmosphere is rated as Vacuum. Around 7% of the surface is covered in sheets of water-ice. Mean surface temperature: -102°C.
Mainworld Geography and Topography
Total surface area: 2.9 million km², Land surface area: 2.7 million km², Ice surface area: 200,000 km².
Native Lifeforms
Manus-Irmin System
No world in the system is known to have native life.
Ygg Subsystem
No world in the subsystem is known to have native life.
History & Background (Dossier)
No information yet available.
World starport
Irmin does not have a starport. The Class X Starport is an indication that no starport exists in the system. There are no facilities or services available, and no site marked for landing.
World technology level
Irmin possesses a Technology Level of TL–0.
- These worlds often contain a Proto-Sophont species beginning to establish a nascent civilization and society.
- This world is in its Alpha Period and has not yet been interfered with by a higher technology civilization.
- Common Communication technologies for this TL include: Bodily communicative apparati, courier-runners, and smoke signals.
- Common Power Generation technologies for this TL include: Bodily muscle.
- Common Transportation technologies for this TL include:
- Land: Bodily locomotion, riding beasts, and litters or sedan chairs.
- Water: Swimming, rafts, and canoes.
- Air: Typically not available unless a bodily ability.
World government
Irmin has no central government for the world, an Anarchy. The largest governmental structure would be a family, tribe, or single clan. The largest group will be between 50 and 100 individuals, and there may be dozens to hundreds of them. This governmental structure can be stable over long periods of time if the population remains small or geographically separated.
