Water World

Magnetic FieldExtreme Activity
Why is this a Water World?Your planet has abundant oxygen (41.2%) and hydrogen (17.6%), 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: 41.2% + Hydrogen: 17.6% (water-forming elements)✓ Temperature: 289K (habitable range)✓ Distance: 0.76 AU (habitable zone)

Abundant liquid water at surface temperature
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
atmosphere100
Nitrogen-oxygen atmosphere - breathable and protective
temperature100
Optimal temperature range for liquid water and life
magnetic Field100
Magnetic field provides radiation protection — but the remnant's shock fronts flood this orbit with cosmic rays

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.
