brown dwarfsNewly discovered young brown dwarfs with masses of 50 and 25 times themassof Jupiter orbit each other at a distance of about 20 billion miles(six times the distance of Pluto from the Sun). All previously knownbinary brown dwarfs have orbits that are more than 10 times smaller thanthis pair. Because of the wide separation of these two brown dwarfs,theirorbits are very fragile and they would be easily torn from each other.Therefore, they likely formed the same way as stars, in a relativelygentleand undisturbed manner.
