Libra

Libra [Lat.,=the scales], southern constellation lying on the ecliptic (the sun's apparent path through the heavens) between Virgo and Scorpius; it is one of the constellations of the zodiac . Sometimes depicted as a pair of scales, it is also known as the Balance. The ancient Greeks represented it as the claws of the Scorpion (Scorpius). Zubenelschemal (Beta Librae), which lies between Arcturus and Antares , is the only star observable by the naked eye that has been reported to appear greenish. Libra reaches its highest point in the evening sky in late June.

Libra (abbr. Lib, gen. Librae) A constellation of the zodiac, representing a pair of scales. The Sun lies in Libra for the first three weeks of November. Alpha Librae (Zubenelgenubi) is a wide double. Beta Librae (Zubeneschamali) is the constellation's brightest star, magnitude 2.6. The two star names come from the Arabic meaning ‘southern claw’ and ‘northern claw’, and arise because Libra once represented the claws of the scorpion, Scorpius, which it adjoins. Delta Librae is an Algol Star, an eclipsing binary that varies between magnitudes 4.9 and 5.9 in a period of 2 days 8 hours.
