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: 10.0x EarthTemperature: 99K
Habitability ScoreUninhabitable
Contributing Factors
water60
Water present but mostly frozen
geology60
Some geological activity provides slow nutrient cycling
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature10
Frozen world - minimal potential for complex life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings0.035% - 1.8 radii
Inside the Roche limit (1.92 planet radii): torn apart into a ring system.
Moon 2rings0.028% - 3.3 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 3stableOcean world0.046% - 8.9 radii
Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (27/100).
Moon 4recedingOcean world0.10% - 13.9 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (11/100).
