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.

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 Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature5
Scorching - hot enough to melt lead, though rock stays solid; no chance for life
magnetic Field20
A strong field, but no surface beneath it — there is nothing here for it to shelter

Surface Characteristics
No surface: a cooling failed star, its methane atmosphere absorbing so much red light it would look magenta to the eye
