Aludra - η Canis Majoris (eta Canis Majoris)
Aludra, also designated as η Canis Majoris (eta Canis Majoris), is a double supergiant star in the constellation of Canis Major.
Aludra visual magnitude is 2.45, making it the 88th brightest star in the sky. Thanks to its high brightness, Aludra is clearly visible when observed from locations with dark skyes, and should be also quite easily visible from light polluted areas.
The table below summarizes the key facts about Aludra:
