fau's moons
1 moon
Moon 1Rock · 287,700 km
Planet, moons and orbits drawn to one scale; the smallest moons are enlarged so they can be seen.
Surface. No solid surface - a thick gas envelope wrapped around a small deep core (a mini-Neptune)
Sub-Neptune
✦ efdffff
Your planet is a sub-Neptune: a 6.0x Earth core wrapped in a deep hydrogen-helium envelope, with no solid surface to stand on.Magnetic FieldLow Activity
Sub-Neptunes are the most common planets Kepler found, though our own solar system has none. Too light to be a giant, they still hold on to a thick envelope of light gas over a rocky or icy core.
Classification Criteria:
✓ Mass: 6.0x Earth (under 20x, below the giants)✓ A hydrogen-helium envelope over the core
Habitability ScoreUninhabitable
Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology60
Some geological activity provides slow nutrient cycling
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry20
Limited organic chemistry potential
atmosphere12
Deep hydrogen-helium envelope with photochemical haze
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)temperature20
Extremely hot - hostile to known life forms (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection (a large close moon may help stir the core dynamo (speculative))

Moons
Moon 1receding
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
