This article is about the star. For other uses, see Antares (disambiguation). Antares (/Ã¦nËtÉËriËz/), also designated Alpha Scorpii (Î± Scorpii, abbreviated Alpha Sco, Î± Sco), is on average the fifteenth-brightest star in the night sky, the brightest star in the constellation of Scorpius.
As the summer season wanes, Antaresâ fading into the southwestern dusk presages the cooler days of autumn. In early July, in either the Northern or Southern Hemisphere, Scorpius climbs to its highest point in the sky at about 10 p.m. local time (11 p.m. local Daylight Saving Time).
