Brown dwarfs

A brown dwarf is, in the real world, an astronomical body which is sort of a halfway point between a gas giant and a star. The brown dwarf does put out a little light and heat from fusing deuterium, an isotope of hydrogen, and if it is large enough it can fuse lithium. If the body is massive enough to fuse normal hydrogen, it becomes a star. It is my theory that KSP 2 may have brown dwarfs as well. Assuming an outer limit of 20 light-years in any direction, there will be about 24 brown dwarfs. The ksp 2 trailer did not mention any brown dwarfs.
