Gas Giant
Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 8.9% hydrogen and helium, combined with a mass of 10.0x 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: 8.9% (>60% required)✓ Mass: 10.0x Earth (>10x required)
Habitability ScoreUninhabitable
Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology40
Extreme volcanic activity may be hazardous
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry100
All CHNOPS elements present - building blocks of life (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 pulsar's beams bathe this orbit in hard X-rays

Moons
Moon 1recedingOcean world0.20% - 14.2 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (44/100).
Moon 2recedingOcean world0.050% - 8.6 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (39/100).
Moon 3rings0.010% - 3.6 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 4merged0.050% - 4.3 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
