In the image above, the yellow disk at the center is the Luhman 16 system, the individual brown dwarfs are not resolved.
Luhman 16 is a binary brown-dwarf system in the southern constellation Vela at a distance of approximately 6.5 light-years (2.0 pc) from the Sun. These are the closest known brown dwarfs and the closest system found since the measurement of the proper motion of Barnard's Star in 1916, and the third-closest known system to the Sun (after the Alpha Centauri system and Barnard's Star). The primary is of spectral type L7.5 and the secondary of type T0.5 ± 1 (and is hence near the L–T transition). Luhman 16 A and B orbit each other at a distance of about 3 AU with an orbital period of approximately 25 years.
