Brown Dwarf thought

There is a type of celestial object called a Brown Dwarf. A Brown Dwarf is object that is half way between a star and a planet. There is a very blurry line between a Brown Dwarf and a Red Dwarf. A Red Dwarf is a true star but is the smallest type. Brown Dwarfs are not quite fully working stars, there isn't persistent nuclear fusion in the object's core. 

I was wondering if planet nine was actually a Brown or small red dwarf like object. Although Red Dwarfs make their own light, they are very dim and the smaller ones are very hard to see even with powerful telescopes.  We know that planet nine is out there orbiting our sun and we know it is very big because it is affecting commets over very large distances but we have never seen it and don't know what it is like. 

I imagined a Large Jupiter sized planet with an Earth sized planet  as a moon orbiting it, compared to a Brown Dwarf Jupiter is tiny. Brown Dwarfs and red Dwarfs are huge. 

There is so much mystery out there. This is what I was thinking about today. Just wondering what is out there in deep space.
