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]
