It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.26. The star is moving away from the Earth with a heliocentric radial velocity of +17 km/s, having come to within 45.550NaN0 some 5.5 million years ago. It is positioned near the ecliptic and thus is subject to lunar occultations.
This object is an A-type main-sequence star with a stellar classification of A0 Vnn, where the 'n' notation indicates "nebulous" lines due to rapid rotation. It is spinning with a projected rotational velocity of 149 km/s. This star has around 2.3 times the radius of the Sun and is radiating over three times the Sun's luminosity from its photosphere at an effective temperature of 8,794 K.
