Magnetic Field Low Activity
Why is this a Rocky Terrestrial? Your planet is dominated by silicate (30.0%) and iron (20.0%) content, forming a rocky terrestrial body. Rocky terrestrial planets are primarily composed of silicate rocks and metals. They're the most common type of small planet in the universe.
✓ Silicon: 30.0% + Iron: 20.0% + Magnesium: 0.0% ✓ Mass: 0.5x Earth (terrestrial range)
Habitability Score Extremely Harsh
Contributing Factors water 21
Limited water content - frozen solid, no liquid phase at this temperature geology 60
Some geological activity provides slow nutrient cycling rotation 10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only Organic Chemistry 84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry) atmosphere 28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation) temperature 40
Extreme temperature - very difficult for life magnetic Field 100
