Brown dwarf

From Vinidia

Brown dwarf are celestial objects to massive to be a planet but not massive enough to be a star. These objects are commonly called as sub-stellar objects due to their nature. Most of them are not massive enough to sustain or even initiate hydrogen fusion but they are able to start a limited form of thermonuclear reaction by fusing hydrogium, deuterium or lithium. A typical brown dwarf has a mass of between of 8 MJ to 75 MJ, below that mass objects will become a planet and above that they are stars.
