11 Canis Majoris is a single [7] star in the southern constellation of Canis Major, the eleventh entry in John Flamsteed's catalogue of stars in that constellation. It has a blue-white hue and is visible to the naked eye with an apparent visual magnitude of 5.28. [2] The distance to this star is approximately 1,010 light years from the Sun based on parallax, [1] and it is drifting further away with a radial velocity of around +15 km/s. [4] It has an absolute magnitude of −1.63. [2]
This star has a stellar classification of B8/9III, [3] matching a B-type star that is in the giant stage. It has a high rate of spin with a projected rotational velocity of 130 km/s. [5] The star is radiating 485 [2] times the luminosity of the Sun from its photosphere at an effective temperature of 11,540 K. [5]
