Brown dwarfs are distinct objects that are more massive than Jupiter but lack sufficient mass to stably fuse hydrogen at their cores.

“stars that are too low mass to stably fuse hydrogen at their cores.”

Brown dwarfs are objects that failed to accumulate enough mass to sustain nuclear fusion and instead gradually cool throughout their existence.

“they don't have enough mass to get the core hot enough to get nuclear burning going but they do it anyway no no this is they think they're going to be a star but they're not so whatever now you guys are putting a motion on it don't know what they should or shouldn't be they're just existing”
