=== System Data ===
==== H'ssakth System ====
The primary is H'ssakth, a red giant [[star]]. It has a luminosity of 1194 Sols, a mass of 6.74 Sols, and a diameter of 179.49 million km – the corona of the star extends to 0.6 AU, within orbital position (III). The inner system consists of (V) a [[vacuum]] [[worldlet]], (VI) a [[trace atmosphere]] [[inner world]], (VII) a [[corrosive atmosphere]] [[inferno world]], and (VIII) a dense stony [[planetoid belt]] – orbital positions (I) and (II) lie within the star and orbital positions (III) and (IV) are empty. (IX) a [[ring]]ed [[large gas giant]] orbits within the [[habitable zone]]. (X-I) a [[small gas giant]], and (X-II) an [[corrosive atmosphere]] [[bigworld]] form the outer system. Many of the worlds retain [[satellite]]s

==== K'thaa-Ssihka Subsystem ====
The companion is K'thaa, an ordinary red main sequence [[star]] lying approximately 780 AU from H'ssakth. It has a luminosity of 0.0268 Sols, a mass of 0.4258 Sols, and a diameter of 658,000 km. (I) Ssihaa, designated the [[mainworld]], (II) a [[very thin atmosphere [[radworld]], (III) an [[exotic atmosphere]] [[bigworld]], and (IV) a small [[ice giant]] form the outer system. Most of the worlds retain [[satellite]]s.
* The star experiences periodic flare activity.

=== Mainworld Data ===
==== (I) Ssihaa ====
(I) Ssihaa is designated the [[mainworld]]. It orbits K'thaa at a mean distance of 0.16 AU (23.9 million km), within the [[habitable zone]]. It has an orbital period of 34 days 18 hours: it is [[tidally locked]] to K'thaa. The axial tilt is 0 degrees. Ssihaa has a diameter of 4,699 km, a density of 5.21 g/cm³, and a surface gravity of 0.35 G. Tidal stresses generated by the gravitational pull of K'thaa cause frequent geological activity. Its atmosphere is rated as [[Very thin atmosphere|Very Thin]], [[Tainted atmosphere|Tainted]], with a mean surface pressure of 0.18 bar and a composition of 87% nitrogen (N<sub><small>2</small></sub>), 11% abiotic oxygen (O<sub><small>2</small></sub>), 1% argon (Ar), and 1% carbon dioxide (CO<sub><small>2</small></sub>), water vapor (H<sub><small>2</small></sub>O), ozone (O<sub><small>3</small></sub>), neon (Ne) and other trace gases. The [[Tainted atmosphere|taint]] is caused by the very low percentage of atmospheric oxygen and the relatively high levels of background radiation: emission rates exceed 3 rads per hour. Approximately 21% of the surface is covered in sheets of water ice and lakes of liquid water. Mean surface temperature: -3°C. The [[Fringian_Variant_System_Description#Planetary_Climate|climate]] is rated as Cold and is static, with no seasonal changes during the local year. The atmosphere is sluggish and weak weather systems driven by the star drift across the globe.

==== Mainworld Geography and Topography ====
Total surface area: 69 million km², Land surface area: 55 million km², Water surface area: 14 million km².
* The oxygen in the atmosphere is abiotic in origin, produced by the photocatalytic reaction between UV energy radiating from the star and titanium dioxide (TiO<sub><small>2</small></sub>), which is found in surface minerals such as ilmenite.
* Ssihaa 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 Zone World|twilight]] region.

=== Native Lifeforms ===
==== H'ssakth System ====
No [[world]] in the [[system]] is known to have native life.

==== K'thaa-Ssihka Subsystem ====
No [[world]] in the [[system|subsystem]] is known to have native life.
