Rocky Terrestrial

Photeron
None Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (36.2%) and iron (21.3%) 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: 36.2% + Iron: 21.3% + Magnesium: 10.6%✓ Mass: 0.1x Earth (terrestrial range)

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology30
Geologically dead - no nutrient recycling
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry20
Limited organic chemistry potential
atmosphere20
CO₂ atmosphere with moderate greenhouse effect (partially stripped by slow rotation)
temperature75
Challenging but potentially habitable temperature (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))

Moons
Moon 1receding10% - 21.6 radii

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

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