Word Origin and History for canopus

Canopus

n.

bright southern star, 1550s, ultimately from Greek Kanopos, Kanobos perhaps from Egyptian Kahi Nub "golden earth." The association with "weight" found in the name of the star in some northern tongues may reflect the fact that it never rises far above the horizon in those latitudes. Also the name of a town in ancient lower Egypt (famous for its temple of Serapis), hence canopic jar, canopic vase, which often held the entrails of embalmed bodies (1878).
