Gas Giant

✦ Kalius
Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 93.8% 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: 93.8% (>60% required)✓ Mass: 10.1x 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
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature0
Inferno world - temperatures exceed all possibility of life
magnetic Field100
Magnetic field provides radiation protection

Surface views from three worlds: rocky ground under a ringed sky, a cloud deck, and a lit desert

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.
