Inselm is an icy, nonindustrial vacuum world, warranting hazardous environment precautions.

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

System Data[edit]

Armilam-Inselm System[edit]

The primary is Armilam, a dim red main sequence star. It has a luminosity of 0.004 Sols, a mass of 0.273 Sols, and a diameter of 414,000 km. (I) a vacuum iceworld, (II) Inselm, designated the mainworld, (III) a small gas giant: (IV) a ringed large gas giant, (V) a small ice giant, and (VI) a trace atmosphere worldlet form the outer system. Many of the worlds retain satellites.

  • The star experiences periodic flare activity.

Obbo Subsystem[edit]

The companion is Obbo, a dwarf star that lies approximately 87.8 AU (orbital position (XI), 13.11 billion km). It has a luminosity of 0.00003 Sols, a mass of 1.12 Sols, and a diameter of 8,400 km. (I) a dense icy planetoid belt forms the outer system.

Mainworld Data[edit]

(II) Inselm[edit]

(II) Inselm is designated the mainworld. It orbits Armilam at a mean distance of 0.45 AU (67.33 million km), within the outer system. It has an orbital period of 211 days 0 hours: it is tidally locked to Armilam. The axial tilt is 3 degrees. Inselm has a diameter of 3,175 km, a density of 6.84 g/cm³, and a surface gravity of 0.31 G. Tidal stresses generated by the gravitational pull of Armilam cause occasional geological activity. Its atmosphere is rated as Vacuum. Approximately 9% of the surface is covered in sheets of crystalline water-ice. Mean surface temperature: -110°C.

Mainworld Geography and Topography[edit]

Total surface area: 32 million km², Land surface area: 29 million km², Ice surface area: 3 million km².

  • Inselm is a Twilight Zone World.
  • The world experiences libration, which causes the star to move in the sky and periodically rise and fall above the horizon in the twilight region.

Native Lifeforms[edit]

Armilam-Inselm System[edit]

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

Obbo Subsystem[edit]

  • 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. Such ports rarely have more than one of each kind of port.

World technology level[edit]

Inselm possesses a Technology Level of TL–11 or TL-B in Hexadecimal Notation.
