Star Identification


The brightest stars of a constellation are identified by a Greek letter. Beginning with alpha, stars are assigned letters primarily by decreasing magnitude. A particular star can be identified by naming the Greek letter and then the genitive form of the contellation, or its abbreviation. For example, the brightest star in the contellation Centaurus is Alpha Centauri, or Alpha Cen for short. In addition to these systematic names, many stars also have Arabic names.

The following table lists the letters of the Greek alphabet.
