System Data[edit]

Iis'kiih-Thi'aa System[edit]

The primary is Iis'kiih, an ordinary orange main sequence star. It has a luminosity of 0.284 Sols, a mass of 0.723 Sols, and a diameter of 1.073 million km. The inner system consists of (I) an exotic atmosphere radworld, and (II) an exotic atmosphere hospitable world. (III-I) Thi'aa, designated the mainworld, and (III-II) a corrosive atmosphere inferno world have a shared orbit within the habitable zone. (IV) a very thin atmosphere hospitable world, (V) a trace atmosphere iceworld, (VI) a ringed very large gas giant, (VII) a small gas giant, and (VIII) a vacuum worldlet form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(III-I) Thi'aa[edit]

(III-I) Thi'aa is designated the mainworld. It orbits Iis'kiih at a mean distance of 0.58 AU (86.8 million km), within the habitable zone. It has an orbital period of 263 days 6 hours and a rotation period of 27.5 hours. The axial tilt is 22 degrees. Thi'aa has a diameter of 7,792 km, a density of 4.79 g/cm³, and a surface gravity of 0.53 G. The world is geologically active. Its atmosphere is rated as Very Thin, with a mean surface pressure of 0.27 bar and a composition of 80% nitrogen (N2), 19% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. Approximately 48% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.2m. Mean surface temperature: 27°C. The atmosphere is active and moderate weather systems driven by the star and the seas work across the globe. The climate is seasonal.


Thi'aa retains two natural satellites, a vacuum worldlet named Ko and an ice-capped vacuum worldlet named Shi'kaha:

(III-Ia) Ko (known UWP ?200???-?, orbiting at 12 Diameters/94,000 km)
(III-Ib) Shi'kaha (known UWP ?301???-?, orbiting at 20 Diameters/156,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 191 million km², Land surface area: 99 million km², Water surface area: 92 million km².

Native Lifeforms[edit]

Iis'kiih-Thi'aa System[edit]

Thi'aa, 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.

The cold marginally hospitable world lying in orbital position (IV) has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find even a minimal trace of shelter and warmth. Their metabolic functions maintain the process of atmospheric renewal.

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