Gas Giant
✦ GresmondMagnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 69.6% hydrogen and helium, combined with a mass of 42.0x Earth, which exceeds the gas giant threshold.
Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.
Classification Criteria:
✓ Hydrogen + Helium: 69.6% (>60% required)✓ Mass: 42.0x Earth (>10x required)
Habitability ScoreExtremely Harsh
Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology50
Extreme volcanic activity may be hazardous (tidal flexing sustains geologic activity)
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)
temperature100
Optimal temperature range for liquid water and life
magnetic Field100
Magnetic field provides radiation protection — but the black hole's accretion disk bathes this orbit in hard X-ray radiation

Moons
Moon 1stableOcean world0.014% - 6.9 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 (42/100).
Moon 2stable0.010% - 12.8 radii
Small and distant: a quiet, stable companion.
Moon 3rings0.010% - 1.8 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 4merged0.028% - 7.1 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 5stable0.00013% - 17.5 radii
Small and distant: a quiet, stable companion.
Moon 6merged0.00022% - 7.1 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 7rings0.050% - 4.9 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
