Aludra (Eta Canis Majoris) Map © 2003 Torsten Bronger A supergiant B star and the fifth brightest star in the constellation Canis Major.

Beta Canis Majoris is the prototype star for a certain class of oscillating, variable stars characterized by a multiplicity of periods. Burnham says that there is relation between period and luminosity as with the better known Cepheid variables.

Beta Canis Majoris is also of some interest. Its name, "Murzim" means "The Announcer", as its appearance on the horizon signifies the approach of Sirius. This is a pulsating giant that has become the prototype of a class of variable stars (see below).

It can be found: east of Sirius; southwest of Procyon; northeast of Wezen (Delta Canis Majoris), Aludra (Eta Canis Majoris), and Adhara (Epsilon Canis Majoris); and north of Naos (Zeta Puppis).
