[2] The system is approximately 340 light years away from the Sun based on parallax.

It is moving further from the Earth with a heliocentric radial velocity of +29 km/s,[4] having come to within 69 light-years some three million years ago.

[6] It is radiating 300 times the luminosity of the Sun from its expanding photosphere at an effective temperature of 7,161 K.[6] It has one suspected companion, component B, at a separation of 0.3".
