HD 78004 .
HR 3407 is a single[ 10] star in the southern constellation of Vela . It has the Bayer designation C Velorum ; HR 3407 is the designation in the Bright Star Catalogue [ 9] apparent visual magnitude of 5.01.[ 2] 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] [ 6] mass of the Sun and has expanded to around 71[ 1] 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] [ 4] luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,324 K.[ 1]
