description Zubenelgenubi Overview

Zubenelgenubi, officially designated Alpha Librae, is a wide binary star system located in the zodiac constellation of Libra. The primary star is a blue-white main-sequence star, while its companion is a fainter star visible under clear night skies. The system's traditional name is derived from an Arabic phrase translating to "southern claw," reflecting its historical placement in Scorpius before modern boundaries were established. The two primary stars are separated by a large physical distance and orbit each other over a vast period of time.
