HII 1348 is a highly eccentric double-lined spectroscopic binary (P = 94.805 d, e = 0.5543) with a nearly identical companion star (Queloz et al. 1998, Torres et al. 2021) and an outer circumbinary substellar companion. A third M dwarf companion star (HII 1348 C) lies 5155 AUs away and the triple system is in turn orbited by an additional, outer substellar object (HII 1348 D or (ABC)b).
