EZ Canis Majoris is a Wolf–Rayet star of spectral type WN4 that varies between magnitudes 6.71 and 6.95 over a period of 3.766 days; the cause of its variability is unknown but thought to be related to its stellar wind and rotation. [63] VY Canis Majoris is a remote red hypergiant located approximately 3,800 light-years away from Earth.
In Greek and Roman mythology and religion, Sirius (/ ˈ s ɪ r ɪ ə s /, SEE-ree-əss; Ancient Greek: Σείριος, romanized: Seírios, lit.

Epsilon Canis Majoris is a binary star system and the second-brightest star in the constellation of Canis Major. Its name is a Bayer designation that is Latinised from ε Canis Majoris, and abbreviated Epsilon CMa or ε CMa. This is the 22nd-brightest star in the night sky with an apparent magnitude of 1.50.
Despite its large size compared to the Sun, Antares is dwarfed by even larger red supergiants, such as VY Canis Majoris, KY Cygni, RW Cephei or Mu Cephei. Antares, like the similarly sized red supergiant Betelgeuse in the constellation Orion, will almost certainly explode as a supernova, [61] probably in 1.0 to 1.4 million years. [10]
