Rocky Terrestrial
✦ PhoteronNone 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)
Habitability ScoreUninhabitable
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.
Moon 2merged0.010% - 45.0 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3merged0.010% - 59.2 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 4merged0.010% - 76.1 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 5stable0.010% - 93.9 radii
Small and distant: a quiet, stable companion.
