[1] It is visible to the naked eye as a dim, white-hued star with a combined apparent visual magnitude of 5.00.
[10] Cowley et al. (1969) found a stellar classification of A7 V[5] for the visible component, matching an A-type main-sequence star that is generating energy through hydrogen fusion at its core.
Abt and Morrell (1995) instead listed a class of A6 IV,[4] suggesting it has left the main sequence and become a subgiant star.
It is 401 million years old with a high rate of spin, showing a projected rotational velocity of 85 km/s.
Its effective temperature also vary across its surface due to rotation, from 8,200 K in the poles to 8,000 K in the equator.
