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
geology30
Geologically dead - no nutrient recycling
rotation25
Very fast rotation - perpetual hurricane-force winds, extreme Coriolis effects, hazardous for complex life
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature0
Inferno world - temperatures exceed all possibility of life
magnetic Field20
A strong field, but no surface beneath it — there is nothing here for it to shelter

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
