Quadruple system. The inner pair is is an accentric (e = 0.3984) eclipsing binary with P = 17.99628 d. Secondary star is similar to the primary (M2 = 0.986 ± 0.015 MSol, R2 = 0.941 ± 0.005 RSol, T2 = 5714 ± 552 K). The outer binary pair (a ∼167 AUs, P = 16.5 d) is eccentric as well (e = 0.44) and consists in a pair of G dwarfs.
