Rocky Terrestrial Magnetic Field Moderate Activity
Why is this a Rocky Terrestrial? Your planet is dominated by silicate (33.3%) and iron (55.0%) 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: 33.3% + Iron: 55.0% + Magnesium: 0.0% ✓ Mass: 1.0x Earth (terrestrial range)
Habitability Score Uninhabitable
Contributing Factors water 0
No water - the recipe has no hydrogen and oxygen to form it geology 100
Active geology recycles nutrients and drives carbon cycle (tidal flexing sustains geologic activity) rotation 10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only Organic Chemistry 20
Limited organic chemistry potential atmosphere 4
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation) temperature 100
Optimal temperature range for liquid water and life (large moon stabilizes the axial tilt - steady seasons) magnetic Field 100

Surface Characteristics Rocky surface with impact craters, possible volcanic features Moons
Moon 1 rings 2.8% - 2.3 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2 receding 1.6% - 9.7 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
