GW Ori is a hierarchical triple star system with a spectroscopic binary (A,B) at a separation of about 1 AU and a tertiary stellar companion (C) at a projected distance of about 8 AUs. Stars A and B have masses of 2.8 M_Sol and 1.7 M_Sol, respectively, while star C has a mass of 1.2 M_Sol and the eccentricity of the outer companion is estimated to be 0.22.
