 The interferometry-measured angular diameter of this star, after correcting for limb darkening, is , which, at its estimated distance, equates to a physical radius of about 11.5 times the radius of the Sun.Despite having expanded to this radius, Beta Columbae only has about a 10% greater mass than the Sun.The outer envelope of this star is radiating energy at an effective temperature of 4,545 K, resulting an orange hue that is typical of a cool, K-type star.
