System Data
Cho System
The primary is an unnamed 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) a vacuum inner world, and (II) an exotic atmosphere radworld. (III) Cho orbits within the habitable zone and is designated the mainworld. (IV) a small gas giant, (V) a ringed large gas giant, (VI) a dense stony planetoid belt, (VII) a large gas giant, and (VIII) a small ice giant form the outer system. Many of the worlds retain satellites.
Mainworld Data
(III) Cho
(III) Cho is designated the mainworld. It orbits the primary at a mean distance of 0.63 AU (94.3 million km), within the habitable zone. It has an orbital period of 214 days 19 hours and a rotation period of 22 hours. The axial tilt is 164 degrees. Cho has a diameter of 7,522 km, a density of 5.07 g/cm³, and a surface gravity of 0.54 G. The world is geologically active. Its atmosphere is rated as Thin, with a mean surface pressure of 0.72 bar and a composition of 78% nitrogen (N2), 20% oxygen (O2), 1% argon, (Ar), and 1% carbon dioxide (CO2), xenon (Xe), water vapor (H2O), neon (Ne) and other trace gases. Approximately 42% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.4m. Mean surface temperature: 3°C. The atmosphere is slow and moderate weather systems driven by the star and the seas work across the globe. The climate is seasonal.
Satellite
Cho retains a single natural satellite, a trace atmosphere worldlet named Sung:
- (IIIa) Sung (known UWP ?110???-?, orbiting at 5 Diameters/37,000 km)
Native Lifeforms
Cho, the mainworld, lying within the habitable zone, has extensive native life, consisting of microscopic organisms, stromatolite-parallels and primitive flora that can be found in almost every ecological niche. Their metabolic functions drive the process of atmospheric renewal.
History & Background (Dossier)
The Cho system has been studied by the Local Astrographical Survey Project, a part of the Astronomy Department of the University of Selasia.
