Gas Giant
✦ Stargazer NebulaMagnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 69.6% hydrogen and helium, combined with a mass of 10.1x 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: 10.1x 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
geology40
Extreme volcanic activity may be hazardous
rotation30
Very slow rotation - severe temperature swings between eternal day and night sides
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere18
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings0.010% - 1.8 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2stable0.0010% - 4.4 radii
Small and distant: a quiet, stable companion.
Moon 3stableOcean world0.010% - 7.7 radii
Small and distant: a quiet, stable companion.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (2/100).
Moon 4stable0.00056% - 11.3 radii
Small and distant: a quiet, stable companion.
Moon 5receding0.10% - 22.5 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
