TRUE brown dwarfs have about the same radius of jupiter but have masses that are 13 to 80 times bigger than jupiters mass.
Brown dwarfs are less massive than stars but more massive than any of the large planets in our solar system. Although this brown dwarf is about the same size as Jupiter, it spins approximately ten times more quickly and has around 43 times more mass than Jupiter.
Jupiter is the largest planet in our solar system, yet despite its size, it is still much too light to fuse hydrogen into helium. To become a brown dwarf, the planet would need to be 13 times its present mass; to become a low-mass star, it would need to be 83 to 85 times its current mass.
The brown dwarfs that have been found so far are all components of a binary system.
