Teide 1 was considered for some time the smallest object out of the Solar System that had been identified by direct observation. Since then over 1800 brown dwarfs have been identified. Some are very close to Earth such as Epsilon Indi Ba and Bb, a pair of brown dwarfs gravitationally bound to a sunlike star around 12 light-years from the Sun, and WISE 1049-5319 a binary system of brown dwarfs about 6.5 light-years away.
