− | (IIIb) Yedan is the second of the three major moons of Woocha and is designated the [[mainworld]]. It orbits its parent world at a mean distance of 25 diameters (700,000 km) and has an orbital period of 98 days 0 hours: it is [[tidally locked]] to Woocha. It has an axial tilt of 0 degrees relative to Woocha. It has a diameter of 6,681 km, a density of 4.26 g/cm³ and a surface gravity of 0.41 G. Tidal stresses caused by the gravitational pull of Woocha cause frequent seismic activity. It retains an atmosphere rated as [[Very thin atmosphere|Very Thin]], [[Tainted atmosphere|Tainted]], with a surface pressure of 0.18 bar and a composition of 90% nitrogen (N<sub><small>2</small></sub>), 8% | + | (IIIb) Yedan is the second of the three major moons of Woocha and is designated the [[mainworld]].

It retains an atmosphere rated as [[Very thin atmosphere|Very Thin]], [[Tainted atmosphere|Tainted]], with a surface pressure of 0.18 bar and a composition of 90% nitrogen (N<sub><small>2</small></sub>), 8% oxygen (O<sub><small>2</small></sub>), 1% carbon dioxide (CO<sub><small>2</small></sub>), and 1% argon (Ar), 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 extremely low percentage of oxygen and high levels of carbon dioxide. Around 26% of the surface is covered in thick ice sheets and around 3% is covered in small seas of water kept liquid by salinity and geothermal activity: tidal ranges are negligible. Mean surface temperature: -75°C. The atmosphere is extremely sluggish and marginal weather systems driven by the star drift across the surface. The climate is static. |
