Brown Dwarf

Magnetic FieldNone Activity
Why is this a Brown Dwarf?Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.
Classification Criteria:
Composition doesn't match standard planet typesMass: 6356.0x EarthTemperature: 1427K
Habitability ScoreUninhabitable

Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology30
Geologically dead - no nutrient recycling
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature0
Inferno world - temperatures exceed all possibility of life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1stable0.00032% - 100.0 radii

Small and distant: a quiet, stable companion.

Tidal braking locked the planet to its moon: one face forever moonward.

Moon 2merged10% - 1.7 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 3stable0.00025% - 4.7 radii

Small and distant: a quiet, stable companion.

Moon 4rings0.00063% - 1.5 radii

Inside the Roche limit (1.79 planet radii): torn apart into a ring system.

Moon 5stable0.00010% - 5.4 radii

Small and distant: a quiet, stable companion.

Moon 6stable0.00071% - 2.7 radii

Small and distant: a quiet, stable companion.

Moon 7merged0.010% - 61.7 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 8stable0.010% - 60.4 radii

Small and distant: a quiet, stable companion.

Moon 9stable0.010% - 81.1 radii

Small and distant: a quiet, stable companion.

Moon 10merged0.010% - 73.0 radii

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.
