HD 121504 is an 8th magnitude star in the constellation of Centaurus. It is a yellow dwarf (spectral type G2V) and remarkably similar to our Sun, only slightly brighter like α Centauri A. However, it is located at a distance for about 140 light years and thus is not visible to the unaided eye; binoculars or small telescope is required to see this star.
Another component, designated as SAO 241323 has been proposed as a component of the system. However, the star is an optical binary component and in reality is a white giant star located thousands of light years away.
