Jirune is an icy, nonindustrial vacuum world, warranting hazardous environment precautions.
- Its surface is ice-capped with little or no atmosphere and nearly all of its water frozen.
- It requires extensive imports of outside technology to maintain a modern, star-faring society.
- It is a Non-Aligned world dominated by human sophonts located in the Annistu Subsector of Far Home Sector.
- This world is controlled by Sal Marda
Astrography and Planetology
This star system is detailed using the Fringian Variant System Description.

System Data
Velovo-Jirune Systm
The primary is Velovo, 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 trace atmosphere radworld, (II) a sparse stony planetoid belt, (III) Hasa, a ringed large gas giant: Jurune is its outer moon and is designated the mainworld, (IV) a dense icy planetoid belt, (V-I) an exotic atmosphere bigworld, (V-II) a trace atmosphere iceworld, and (VI) a vacuum worldlet form the outer system. Many of the worlds retain satellites.
(III) Hasa
(III) Hasa is a ringed large gas giant that orbits Velovo at a mean distance of 0.82 AU (122.7 million km), within the outer system, and has an orbital period of 1 year 154 days. It has a diameter of 133,000 km and an atmosphere consisting of 91% hydrogen (H2), 9% helium (He), and less than 1% methane (CH4), carbon monoxide (CO), ammonia (NH3), water vapor (H2O) and other trace gases. It is a brown-tan color with broad pale bands, with a number of large semi-permanent equatorial storms. It retains a family of three major satellites.
Satellites
Hasa retains three major satellites:
- (IIIr) Ring System (UWP YR00000-0, extending to 2 Diameters/265,000 km)
- (IIIa) Malasa (UWP Y101000-0, orbiting at 6 Diameters/800,000 km)
- (IIIb) Jirune (designated the mainworld, orbiting at 11 Diameters/1.45 million km)
- (IIIc) Inik (UWP Y4A0000-0, orbiting at 13 Diameters/1.73 million km)
Mainworld Data
(IIIb) Jirune
(IIIb) Jirune is the second of the three major moons of (III) Hasa and is designated the mainworld. It orbits its parent world at a mean distance of 11 diameters (1.45 million km), with an orbital period of 134 days 1 hour: it is tidally locked to Hasa. The axial tilt is 4 degrees relative to Hasa. Jirune has a diameter of 3,016 km, a density of 5.88 g/cm³ and a surface gravity of 0.25 G. Tidal stresses generated by the gravitational pull of Hasa cause occasional geological activity. The atmosphere is rated as Vacuum. Around 18% of the surface is covered in sheets of water-ice. Mean surface temperature: -135°C.
Mainworld Geography and Topography
Total surface area: 28.6 million km², Land surface area: 23.5 million km², Ice surface area: 5.1 million km².
Native Lifeforms
Velovo-Jirune Systm
No world in the system is known to have native life.
History & Background (Dossier)
No information yet available.
World starport
Jirune has a Class E Starport, a frontier quality installation with few expected amenities. There is unrefined fuel for starships and a limited variety of ship provisions. There is no shipyard of any kind, but there may be parts and technical support for doing minor services and repair. Ports of this classification generally consist of a downport.
World technology level
Jirune 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 gills.
- Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
- Space: SSTO spacecraft, early military spacecraft (System Craft), and interstellar STL starships
- FTL: Prototype Jump Drive-1.
World government
Jirune has a Captive Government or Colony. The world is ruled by an external government, there is no self-rule. A colony or conquered area. The local government is an oligarchy appointed by, and answerable only to, the external government.
