Kumura is a fluidic hellworld of sophonts struggling to survive in a inhospitable environment.

  • A fluid world has an oceanic geography of a liquid other than water such as ammonia, methane, hydrocarbons, or other exotic liquids.
  • Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants.
  • It is an unclaimed Non-Aligned world located in the Sithula Subsector of Divide Sector.

System Data[edit]

Kumura System[edit]

The primary is an unnamed hot blue-white main sequence star. It has a luminosity of 60.4 Sols, a mass of 2.94 Sols, and a diameter of 3.673 million km. The inner system consists of (II) a trace atmosphere inner world, (IV) a trace atmosphere worldlet, (V) a corrosive atmosphere inferno world, (VI) an exotic atmosphere radworld, and (VII) a corrosive atmosphere inferno world – orbital positions (I) and (III) are empty. (VIII) Kumura orbits within the habitable zone and is designated the mainworld. (IX-I) a dense stony planetoid belt, (IX-II) a ringed small gas giant, and (X) a small ice giant form the outer system. Many of the worlds retain satellites.

Red Subdwarf Subsystem[edit]

The companion is an unnamed dim red subdwarf star that lies approximately 2,700 from the primary. It has a luminosity of 0.00103 Sols, a mass of 0.081 Sols, and a diameter of 109,000 km. (I) a vacuum worldlet, (II) an exotic atmosphere bigworld, and (IV) a vacuum iceworld form the outer system – orbital position (III) is empty. The bigworld retains satellites.

Mainworld Data[edit]

(VIII) Kumura[edit]

(VIII) Kumura is designated the mainworld. It orbits the primary at a mean distance of 9.7 AU (1.45 billion km), within the habitable zone. It has an orbital period of 17 years 226 days and a rotation period of 35 hours. The axial tilt is 43 degrees. Kumura has a diameter of 10,099 km, a density of 6.74 g/cm³, and a surface gravity of 0.97 G. The world is geologically active. Its atmosphere is rated as Exotic, with a mean surface pressure of 0.74 bar and a composition of 91% nitrogen (N2), 6% carbon dioxide (CO2), 2% abiotic oxygen (O2), and 1% argon (Ar), water vapor (H2O), neon (Ne) and other trace gases. Approximately 21% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.25m. Mean surface temperature: 53°C. The atmosphere is very active and violent weather systems driven by the star and the seas scour the globe. The climate is seasonal.

Satellite[edit]

Kumura retains a single natural satellite, an ice-capped vacuum worldlet named Jonku:

(VIIIa) Jonku (known UWP ?201???-?, orbiting at 45 Diameters/455,000 km)

Native Lifeforms[edit]

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