Water World

Photeron
Magnetic FieldModerate Activity
Why is this a Water World?Your planet has abundant oxygen (37.6%) and hydrogen (21.2%), 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: 37.6% + Hydrogen: 21.2% (water-forming elements)✓ Temperature: 296K (habitable range)✓ Distance: 2.16 AU (habitable zone)

Contributing Factors
water100
Abundant liquid water at surface temperature
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry100
All CHNOPS elements present - building blocks of life (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere100
Nitrogen-oxygen atmosphere - breathable and protective
temperature100
Optimal temperature range for liquid water and life
magnetic Field100
Magnetic field provides radiation protection
