Marginal Gas Giant
Gas Dwarf
Magnetic FieldLow Activity
Why is this a Gas Dwarf?Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.
Classification Criteria:
Composition doesn't match standard planet typesMass: 3.0x EarthTemperature: 216K
Habitability ScoreMarginal
Contributing Factors
water60
Water present but mostly frozen
geology70
Some geological activity provides slow nutrient cycling (tidal flexing sustains geologic activity)
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature40
Extreme temperature - very difficult for life
magnetic Field100
Magnetic field provides radiation protection

Surface Characteristics
No solid surface - a thick gas envelope wrapped around a small deep core (a mini-Neptune)Moons
Moon 1receding0.10% - 9.3 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 2merged0.34% - 11.0 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3receding0.10% - 19.4 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 4stable0.046% - 100.0 radii
Small and distant: a quiet, stable companion.
Moon 5receding0.10% - 33.6 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 6merged0.11% - 41.4 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
