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.
If you think youâve found Antares, aim binoculars in its direction. You should notice its reddish color. And you should see a little star cluster â known as M4 â just to the right of this star. (See images above) Antares is the 16th brightest star in the sky, and it is located in the southern half of Earthâs sky. So your chance of seeing this star on any given night increases as you go farther southward on Earthâs globe.
