Since then, over 1,800 brown dwarfs have been identified, even some very close to Earth like Epsilon Indi Ba and Bb, a pair of brown dwarfs gravitationally bound to a Sun-like star 12 light-years from the Sun, and Luhman 16, a binary system of brown dwarfs at 6.5 light-years from the Sun. See more Brown dwarfs (also called failed stars) are substellar objects that are not massive enough to sustain nuclear fusion of ordinary hydrogen ( H) into helium in their cores, unlike a main-sequence star. Instead, they have a mass … See more The standard mechanism for star birth is through the gravitational collapse of a cold interstellar cloud of gas and dust.
