Gas Giant

✦ Destina
Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 65.0% hydrogen and helium, combined with a mass of 36.0x 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: 36.0x Earth (>10x required)

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
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection

Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).

New: Stand on Your World 🏔️

Every planet you build can now be seen from the ground. The terrain, the color of the sky, the weather and what hangs overhead are all read from the same numbers that shape the globe — so a thin-aired world gives you sunlit rock under a near-black sky crowded with stars, a runaway greenhouse seals you under an unbroken sulfur lid, and a gas giant leaves you in the cloud tops with nothing solid beneath you at all. If one of your moons wandered inside the Roche limit, what is left of it arcs overhead as rings.
