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

• The mainworld.
• x5 secondary rocky worlds.
• x4 gas giants.

Mainworld Data

The mainworld orbits within the two star's combined habitable zone Habitable Zone.

• It lies within the zones colder outer H- region.
• It receives lower levels of stellar energy.

• The world orbits just beyond the two stars Jump Shadow.
• Local temperatures can vary considerably depending on the two stars alignment relative to the world.

Mainworld Size (S)

Chelin is a Small World between 900km and 2,400km in diameter. The world has very low gravity between 0.05G and 0.09G. The horizon will appear about 2km away.

Mainworld Atmosphere (A)

Chelin has a pressure of less than 0.1 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.
