Spectral type L4. Secondary component of a binary system made of two L-type brown dwarf separated by 10 AUs and tracing a far-flung circumbinary orbit around star HD 2057. Gomes et al. (2013) infer that the two resolved brown dwarfs might actually be unresolved binaries themselves, thus making it a possible quadruple substellar system.
