Rocky Terrestrial

None Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (40.5%) and iron (20.3%) 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.
Classification Criteria:
✓ Silicon: 40.5% + Iron: 20.3% + Magnesium: 12.7%✓ Mass: 0.2x Earth (terrestrial range)

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology40
Geologically dead - no nutrient recycling (tidal flexing sustains geologic activity)
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry20
Limited organic chemistry potential
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature45
Extreme temperature - very difficult for life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field35
No magnetic field - vulnerable to solar radiation (a large close moon may help stir the core dynamo (speculative))

Moon 1receding10% - 12.8 radii

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).

Tidal braking locked the planet to its moon: one face forever moonward.
