It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.42, and it is located at a distance of approximately 500 ly pc off on from Sun. The star is moving closer to the Earth with a heliocentric radial velocity of −39 km/s, and may come as close as 41.73 pc ly 0 out off in around 3.5 million years. The visible component is an A-type main sequence star with a stellar classification of A1 V. It has 3.25 times the mass of the Sun and about twice the Sun's radius. The projected rotational velocity is relatively low at 23 km/s. The star is radiating 214 times the luminosity of the Sun from its photosphere at an effective temperature of 9,908 K.
