System Data[edit]

The primary is an unnamed ordinary white main sequence star. It has a luminosity of 4.42 Sols, a mass of 1.38 Sols, and a diameter of 2.031 million km. The inner system consists of (I) a vacuum worldlet, (II) a vacuum inner world, (III) an exotic atmosphere radworld, and (IV) a sparse stony planetoid belt. (V) Geru orbits within the habitable zone and is designated the mainworld. (VI) a dense stony planetoid belt, (VII) a trace atmosphere iceworld, (VIII) an exotic atmosphere bigworld, and (IX) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(V) Geru[edit]

(V) Geru is designated the mainworld. It orbits the primary at a mean distance of 1.51 AU (225.9 million km), within the habitable zone. It has an orbital period of 1 year 212 days and a rotation period of 29 hours. The axial tilt is 3 degrees. Geru has a diameter of 11,212 km, a density of 5.57 g/cm³, and a surface gravity of 0.89 G. The world is geologically active. Its atmosphere is rated as Thin, with a mean surface pressure of 0.68 bar and a composition of 79% nitrogen (N2), 19% oxygen (O2), 1% argon (Ar), and 1% water vapor (H2O), carbon dioxide (CO2), ozone (O3), neon (Ne) and other trace gases. Approximately 84% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.3m. Mean surface temperature: 8°C. The atmosphere is active and strong weather systems driven by the star and the oceans drive across the globe. The climate is static.


Geru retains a single natural satellite, a large exotic atmosphere hospitable world named Depecor:

(Va) Depecor (known UWP ?5A0???-?, orbiting at 45 Diameters/500,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 395 million km², Water surface area: 332 million km², Land surface area: 63 million km².

Native Lifeforms[edit]

Geru, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.
