It lies approximately 560 light years away and is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of 5.047.

[2] The star is moving closer to the Sun with a heliocentric radial velocity of −23 km/s, and may come as close as 198 light-years in 5.9 million years.

[5] This is a subgiant star with a spectral class of B5 IV,[3] indicating a hot massive star that has started to evolve away from the main sequence after exhausting it core hydrogen.

[10] The star has five[2] times the mass of the Sun and is spinning rapidly with a projected rotational velocity of 285 km/s.

[7] It is radiating 713 times the Sun's luminosity from its photosphere at an effective temperature of 15,200 K.[2]
