Sigma Librae (σ Librae, abbreviated Sigma Lib, σ Lib) is a binary star in the constellation of Libra. Brachium was known as Gamma Scorpii before it was designated as Sigma Librae in the mid-19th century. What is the temperature of the stars in the constellation of Libra? This is a list of Arabic star names.In Western astronomy, most of the accepted star names are Arabic, a few are Greek and some are of unknown origin. temperature of the B dwarf of 10,100 Kelvin and a distance of 294 light years (give or take 16, orbital data giving 323), the B star It lies at an approximate distance of 154.3 light years from Earth. A constellation is a group of stars, which might form a pattern or shape within a specific area of the sky and is often named after people, animals or objects. Confluence overview for Fermi Gamma-Ray Space Telescope. It has the traditional name Zuben Elakribi , a variant of the traditional name of Gamma Librae .
