Junat is a nonindustrial, pre-rich desert world with no free-standing water.

  • It still lacks adequate population or other means to expand its economy to a rich status.
  • It requires extensive imports of outside technology to maintain a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.
  • This a "low technology" world with technology competency well below technology standards for Charted Space.
  • It is a Non-Aligned world dominated by human sophonts located in the Natar Subsector of Far Home Sector.

System Data[edit]

Quilik-Junat System[edit]

The primary is Quilik, a yellow-white subgiant star. It has a luminosity of 7.6 Sols, a mass of 1.8 Sols, and a diameter of 3.506 million km. The inner system consists of (I) a vacuum worldlet, (II) a trace atmosphere worldlet, (III) a corrosive atmosphere inferno world, (IV) a sparse stony planetoid belt, and (V) a very thin atmosphere hospitable world. (VI) Nettuni, an exotic atmosphere bigworld, orbits within the habitable zone: (IVa) Junat is its only satellite and is designated the mainworld. (VII) a dense rocky planetoid belt, (VIII) a large gas giant, (IX) a ringed small gas giant, and (X) a small ice giant form the outer system. Many of the worlds retain satellites.

(VI) Nettuni[edit]

(VI) Nettuni (UWP YDA2000-0) is designated a bigworld. It orbits Quilik at a mean distance of 2.61 AU (390.5 million km), within the habitable zone. It has an orbital period of 3 years 52 days and a retrograde rotation period of 63 days 6 hours. The axial tilt is 11 degrees. Nettuni has a diameter of 21,405 km, a density of 4.75 g/cm³, and a surface gravity of 1.44 G. The world is geologically active. Its atmosphere is rated as Exotic, with a mean surface pressure of 4.88 bar and a composition of 95% nitrogen (N2), 3% carbon dioxide (CO2), 1% methane (CH4), and 1% argon (Ar), abiotic oxygen (O2), water vapor (H2O), nitrogen dioxide (NO2), azane (NH3), carbon monoxide (CO), ethane (C2H6), acetylene (C2H2) and other trace gases. Approximately 16% of the surface is covered in lakes and seas of ammonium hydroxide (NH4OH) (ammonia water). Mean surface temperature: 73°C. The climate is rated as Very Hot and experiences minor seasonal changes during the local year. The atmosphere is very active and powerful weather systems driven by the star scour the globe.


Nettuni retains a single natural satellite:

(VIa) Junat (designated the mainworld, orbiting at 35 Diameters/750,000 km)

Mainworld Data[edit]

(VIa) Junat[edit]

(VIa) Junat is the only major moon of (VI) Nettuni and is designated the mainworld. It orbits its parent world at a mean distance of 35 diameters (750,000 km), with an orbital period of 59 days 22 hours: it is tidally locked to Nettuni. The axial tilt is 2 degrees relative to Nettuni. Junat has a diameter of 6,236 km, a density of 5.45 g/cm³ and a surface gravity of 0.48 G. Tidal stresses generated by the gravitational pull of Nettuni cause frequent geological activity. The atmosphere is rated as Standard, with a mean surface pressure of 0.94 bar and a composition of 77% nitrogen (N2), 21% oxygen (O2), 1% argon (Ar), and 1% carbon dioxide (CO2), water vapor (H2O), ozone (O3), neon (Ne) and other trace gases. Junat is a desert world: around 9% of the surface is covered in lakes of warm liquid water. Mean surface temperature: 48°C. The climate is rated as Hot and is static, with no seasonal changes during the local year. The atmosphere is active and strong weather systems driven by the star sweep across the globe.

Mainworld Geography and Topography[edit]

Total surface area: 122 million km², Land surface area: 111 million km², Water surface area: 11 million km².

Native Lifeforms[edit]

Quilik-Junat System[edit]

The hot marginally hospitable world lying in orbital position (V) (within the H– region of the inner system) has primitive extremophile native life, consisting entirely of microscopic cyanobacteria-parallels that thrive in the extremely harsh conditions. Their metabolic functions drive the process of atmospheric renewal.

Junat, the mainworld, has extensive native life, consisting of minute multicellular organisms that can be found in most ecological niches. Their metabolic functions drive the process of atmospheric renewal.

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

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Junat 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[edit]

Junat possesses a Technology Level of TL–3.

World government[edit]

Junat is governed by Self-Perpetuating Oligarchy. A single family or small group provides the leadership and important positions in the government. These positions are inherited by member of the group or their family members. The organization may be monarchy, with titles passed to family members. Or a plutocracy where inheritance of the family fortune includes government position. Or the organization may be more typical organization with positions of power inherited.
