HD 150136 is a triple system of massive O-type stars[5] in the southern constellation of Ara. It consists of a double-lined spectroscopic binary[4] with a more distant tertiary companion. The last star is orbiting the other two with a period of 8.2 years, an eccentricity of 0.73, and an inclination of 108°. The estimated masses of the stars are 63±10, 40±6, and 33±12 times the mass of the Sun. This system contains the brightest stars in the NGC 6193 cluster.[5]
