10 Canis Majoris is a single

apparent visual magnitude of 5.23.[3] It is moving away from the Earth with a heliocentric radial velocity of +34 km/s.[7]

This is a massive

oblate shape with an equatorial bulge that is 5% larger than the polar radius.[15] The axis of rotation is inclined by an angle of 45° to the line of sight from the Earth.[9] Samus et al. (2017) classify it as a Be-type variable star that ranges from a peak visual magnitude of 5.13 down to 5.44 with a rotationally-modulated period of 2.63 days.[4][11]

10 Canis Majoris is 8.2

″ along a position angle of 99°, as of 2015.[16]
