System Data

The worlds of the system have been surveyed. They consist of:

• The mainworld.
• x12 secondary rocky worlds.
• x4 gas giants.

Mainworld Data

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's prime H region.
• It receives moderate levels of stellar energy.

Mainworld Size (S)

Ostreph is a Meso World between 8,800km and 10,400km in diameter. The world has a standard gravity between 0.6G and 0.8G. The horizon will appear about 4.4km away.

• Tidal stresses generated by the world's binary companion cause frequent seismic and geological activity.

Mainworld Atmosphere (A)

Ostreph has a pressure of 0.43 to 0.70 atmospheres. The Thin Atmosphere does not require survival gear although it may be hard on sophonts not accustomed to it.

Mainworld Hydrosphere (H)

Ostreph has 75-85% of its surface covered by liquid water with a few large continents and extensive islands. Wilderness refueling is possible.

Satellites

Ostreph is the major component in a binary planet pair.

• The two worlds have a similar mass.
• The two worlds orbit a barycenter once every few days.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.

Native Lifeforms

Abundant, diverse native life filling every available ecological niche. Its metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)
