Lambda Canis Majoris (λ Canis Majoris) is a solitary,[10] blue-white hued star in the constellation Canis Major. Lambda CMa is visible to the naked eye with an apparent visual magnitude of +4.48.[2] Based upon an annual parallax shift of 7.70 mas as seen from Earth,[1] this star is located about 424 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction of 0.14 due to interstellar dust.[5]
This is a B-type main-sequence star with a stellar classification of B4 V.[3] The star is roughly 40 million years old,[6] and is spinning with a projected rotational velocity of 102 km/s.[3] It has about 5.7[6] times the mass of the Sun and is radiating 560[7] times the Sun's luminosity at an effective temperature of 16,300 K.[3]
