Lambda Canis Majoris

Lambda Canis Majoris is a solitary, blue-white hued star in the constellation Canis Major. Its name is a Bayer designation that is Latinized from λ Canis Majoris, and abbreviated Lambda CMa or λ CMa. This star is visible to the naked eye with an apparent visual magnitude of +4.48. Based upon an annual parallax shift of as seen from Earth, it is located about away from the Sun. At that distance, the visual magnitude is diminished by an extinction of 0.14 due to interstellar dust. It is receding from the Sun with a line of sight velocity of +41 km/s. This is a B-type main-sequence star with a stellar classification of B4 V. The star is roughly 40 million years old, and has a high rate of spin with a projected rotational velocity of 102 km/s. It has about 5 times the mass of the Sun and 4.3 times the Sun's radius. The star is radiating 824 times the Sun's luminosity at an effective temperature of 15,481 K.
