Water World Life possible Magnetic Field Moderate Activity
Why is this a Water World? Your planet has abundant oxygen (28.3%) and hydrogen (15.7%), 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.
✓ Oxygen: 28.3% + Hydrogen: 15.7% (water-forming elements) ✓ Temperature: 343K (habitable range) ✓ Distance: 1.00 AU (habitable zone)
Reading your planet’s atmosphere Dominant elements: O, H, N, Si, C, Fe This is what a telescope would measure while your planet crosses in front of its star: starlight passes through the atmosphere and spreads into a rainbow band. Each dark line marks a wavelength the atmosphere absorbed. Every element absorbs its own signature wavelengths — hydrogen always darkens the same two spots, calcium another pair, and so on. Astronomers match the lines in a real spectrum against a library of these signatures to say what an atmosphere is made of, light-years away, without ever visiting. A deeper line generally means more of that element is present. For a real planet, distance is usually measured by parallax: as Earth orbits the Sun, a nearby star appears to shift very slightly against the distant background stars, and the size of that shift gives its distance directly — the same geometry surveyors use, at an interstellar scale.

Habitability ✓ Conditions could support life This planet’s modelled conditions could support biological processes: stable temperatures, liquid water and the chemistry life as we know it needs. That makes life possible, not present.
