It has the Bayer designation C Velorum; HR 3407 is the designation in the Bright Star Catalogue.[9] It is an orange-hued star that is dimly visible to the naked eye with an apparent visual magnitude of 5.01.[2] The distance to this object is approximately 1,040 light years based on parallax measurements, and it is drifting further away with a radial velocity of 4 km/s.[1]
This object is an aging K-type supergiant star with a stellar classification of K1.5Ib.[3] It has about three[6] times the mass of the Sun and has expanded to around 71[1] times the Sun's radius. The latter is equivalent to 0.33 AU, or about one third the distance from the Sun to the Earth. It is spinning with a projected rotational velocity of 4.1.[8] The star displays microvariability with a period of 10.99 cycles per day and an amplitude of 0.0036 in magnitude.[4] It is radiating around 1,600 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,324 K.[1]
