Part of a widely separated (a = 185 AUs) binary system with an early A type star (spT A2V, T = 9009 K, m = 2.27 M_Sol, r = 2.7 R_Sol). Kervella et al. (2022) report a circumbinary brown dwarf companion at 4,870 AUs as well as a far-flung third companion star 186,000 AUs away ("eps Boo D" or 2MASS J14454000+2615167, spT K4/5).
