System Data

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

• The mainworld.
• x5 secondary rocky worlds.
• x2 planetoid belt.
• x4 gas giants.

Mainworld Data

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's warmer inner H+ region
• It receives higher levels of stellar energy.

• The world orbits beyond the star's Jump Shadow.

Mainworld Size (S)

Rygu is a Meso World between 12,000km and 13,500km in diameter. The world has a standard gravity between 0.8G and 1.1G. The horizon will appear about 5.1km away. Vessels with 1G of thrust should check with local starport authorities before attempting to land using emergency power.

Mainworld Atmosphere (A)

Rygu has a pressure of 1.50 to 2.49 atmospheres. While a Dense Atmosphere requires no survival gear this atmosphere also contains an unusual taint such as disease, a hazardous gas mix, pollutants, or sulfur compounds which requires the use of a Filter Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Rygu has 65-75% of its surface covered by liquid water. It has significant large liquid bodies. Wilderness refueling is possible.

Satellites:

Rygu retains a small vacuum moon.

• It orbits once every few weeks.

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 native life occupying every available ecological niche. Its metabolic functions drive the process of atmospheric renewal.
