Water World

Life DetectedMagnetic FieldExtreme Activity
Why is this a Water World?Your planet has abundant oxygen (25.4%) and hydrogen (13.6%), creating extensive water coverage while in the habitable temperature zone.
Water worlds have deep global oceans covering most or all of their surface. They form when planets have high water content and orbit in the habitable zone.
Classification Criteria:
✓ Oxygen: 25.4% + Hydrogen: 13.6% (water-forming elements)✓ Temperature: 268K (habitable range)✓ Distance: 1.10 AU (habitable zone)

Contributing Factors
water60
Water present but mostly frozen
geology40
Extreme volcanic activity may be hazardous
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry54
Carbon and hydrogen present - organic chemistry possible (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere100
Nitrogen-oxygen atmosphere - breathable and protective
temperature70
Challenging but potentially habitable temperature
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.
