CX CMa (CX Canis Majoris) is a blue variable star in the Canis Major constellation.[1][2] Discovery of this variable is usually credited to German Astronomer Cuno Hoffmeister in 1931, although this remains uncertain.[3]

It is an eclipsing binary of Algol (detached)[4] whose magnitude varies between 9.9 and 10.4 with a period of 0.95462500 day (22.911000 hour).[2] The variability was first discovered in 1931.[5] Doubts arose because of scatter in the data and the small amplitude,[6] but the discovery was confirmed by 1949.[7] Its Algol-type light curve exhibits the O'Connell effect, meaning that there is a magnitude difference between subsequent maxima.[8]

The temperature of the secondary star has been estimated at about 10,600 K and its mass at Шаблон:Solar mass. The spectral type of the secondary star is estimated to be in the B8 to A0 range.[9]
