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:

Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology40
Geologically dead - no nutrient recycling (impact-resurfaced crust)
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)
atmosphere0
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation) (atmosphere partially stripped by the moon impact)
temperature0
Inferno world - temperatures exceed all possibility of life (surface remelted by the moon impact - molten regardless of orbit)
magnetic Field100
Magnetic field provides radiation protection

Surface Characteristics
No surface: a deuterium-burning sphere the size of Jupiter and dozens of times its mass, glowing dull red from its own heat
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.

Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3crashed10% - 1.9 radii
Inside the synchronous orbit: tidal decay dragged it down - it struck the planet ages ago.
