The star has a companion with a magnitude of 9.9 at a separation of 142" that can be seen using a telescope with a 6 cm diameter objective. It itself is also a close binary star. Its distance from Earth is estimated to be 1800 light-years, so its luminosity is therefore 33,000 times greater than that of the Sun.
