This illustration provided by Caltech depicts the orbits of brown dwarf twins, Gliese 229Ba and Gliese 229Bb, with a separation only 16 times larger than the distance between Earth and the Moon.

Astronomers have spotted brown dwarf pairs before, but these two whip around at much closer range. They orbit each other every 12 days, less than the time it takes for the moon to circle the Earth.
