Its apparent magnitude is 4.89, which is bright enough to be faintly visible to the naked eye. The distance to this star, based upon an annual parallax shift of 13.11 0.33 mas, is around 249 light years. The star is moving further from the Sun with a heliocentric radial velocity of +20.5 km/s, having made its closest approach some three million years ago at a distance of 32.7 pc ly flip on. This is an MK-standard star with a stellar classification of B9 IV, matching a subgiant star that is evolving away from the main sequence having exhausted the hydrogen at its core. It has a low projected rotational velocity of 26 km/s. The star is about 248 million years old with three times the mass of the Sun and approximately 2.8 times the Sun's radius. It is radiating around 88 times the Sun's luminosity from its photosphere at an effective temperature of about commas 10520 K.
