HD 151967 is suspected variable star in the southern constellationofAra. It is a sixth magnitude star,[3] which means it is just visible to the naked eye in dark skies. Parallax measurements place it at a distance of approximately 710 light years from the Earth.[2]
This is a red giant with a stellar classification of M1III;[4] it has expanded to 53[6] times the radius of the Sun and radiates 637[7] times the Sun's luminosity. The star varies in brightness by an amplitude of 0.0156 in magnitude over a period of 26 days.[8] The effective temperature of the outer atmosphere is 3,839 K,[7] giving it the ruddy hue of an M-type star.[9]
