    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.

    VY Canis Majoris: 1,420 ± 120 [11] [12] [13] AD An extreme oxygen-rich red hypergiant that has experienced two dimming periods in the 20th century where the star became dimmer by up to 2.5 magnitudes. [14] Potentially the largest known star. [12] There is a possilbility that this size might be a bit overestimated (on the order of 1 sigma).
