Gas Giant
✦ ÍliosMagnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 65.0% hydrogen and helium, combined with a mass of 15.0x 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: 65.0% (>60% required)✓ Mass: 15.0x Earth (>10x required)
Habitability ScoreUninhabitable
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 (impact-resurfaced crust)
rotation30
Very slow rotation - extreme 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)
atmosphere28
Hydrogen-rich atmosphere typical of gas giants (atmosphere partially stripped by the moon impact)
temperature0
Extremely hot - hostile to known life forms (surface remelted by the moon impact - molten regardless of orbit)
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings0.071% - 2.8 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2merged0.063% - 6.9 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3crashed0.056% - 5.9 radii
Inside the synchronous orbit: tidal decay dragged it down - it struck the planet ages ago.
Moon 4rings0.056% - 9.7 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 5receding0.050% - 15.4 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 6receding0.050% - 26.1 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
