Planet

Planet are contained in Star Systems. The population living in them is somewhat interconnected and can form a semi-independent economy.

Key Properties

Core Spin Speed

Some planets have a molten magnetic core, which spins relatively to the surface and thus generates a magnetic field, protecting the population from deadly Cosmic Rays. The derived property is Effective Cosmic Ray Intensity, which is CSS.sub(CRI).max(0). The lower is the ECRI, the cheaper is, most importantly, local construction and life insurance. The magnetic field is also required to retain atmosphere, thus limiting the Atmosphere Bio Quality.

• Unit: Core Spin Speed: [0..inf]
• 0: Complete absense of magnetic field
• 1: Earth-like, protects from 1 Cosmic Ray Intensity, allows for 1 Atmosphere Bio Quality.

Surface Bio Quality

Compatibility of the surface with terran life. Affects agriculture the most.

• Unit: Surface Bio Quality: [-2..1]
• 1: Earth-like surface
• 0: Absense of surface
• -1: Hostile surface (corrosive/bad temperature)
• -2: Extremely hostile surface (requires expensive active countermeasures)

Atmosphere Bio Quality

Compatibility of the atmosphere with terran life. Affects all aspects of life, notably construction costs and life insurance.

• Unit: Atmosphere Bio Quality: [-5..1]
• 1: Earth-like atmosphere, perfectly breathable
• 0: Neutral atmosphere with suitable pressure
• -1: Minor toxicity
• -5: Extremely hostile atmosphere (requires expensive active countermeasures)

Fuel Availability

Level of occurence of Fuel in the planet. Usually much higher in low-CSS planets that were bombarded by nearby stars for billions of years, so if core gets started the fuel availability does not change.
