This star has a stellar classification of B7 III,^[3] which means it is a B-type giant star. However, some sources give it a classification of B7 IV, which would indicate it is a subgiant star. It has 3.7 times the mass of the Sun and is spinning rapidly with a projected rotational velocity of 129 km/s.^[6] The estimated size of the star is 4.7 times the radius of the Sun,^[7] and it shines with around 313 times the Sun's luminosity. The effective temperature of the star's outer atmosphere is 11,803 K,^[6] giving it the blue-white hue of a B-type star.^[9]
