x1 Centauri is a star located in the constellation Centaurus. Its name is a Bayer designation; it is also known by its designations HD 107832 and HR 4712. The apparent magnitude of the star is about 5.32, meaning it is only visible to the naked eye under excellent viewing conditions. Its distance is about 443 ly from Earth based on parallax measurements.

x1 Centauri's spectral type is B8/9V, meaning it is a late B-type main sequence star. These types of stars are a few times more massive than the Sun, and have effective temperatures of about 10,000 to 30,000 K. x1 Centauri is just over 3 times more massive than the Sun
