Libra (pronounced /ˈliːbrə/, Latin: weighing scale, symbol , Unicode ♎) is a constellation of the zodiac. It lies between Virgo to the west and Scorpius to the east. It once represented the claws of Scorpius.
Some features[change | change source]
The brightest stars in Libra form a rectangle:
- α Librae, Zubenelgenubi ("southern claw"), a visual binary;
- β Librae, Zubeneschamali ("northern claw");
- γ Librae, Zubenelakrab ("scorpion's claw");
- σ Librae, Brachium an eclipsing variable.
α and β Librae are the scales' balance beam, and γ and σ are the weighing pans.
σ Librae was formerly known as γ Scorpii even though it is well inside the boundaries of Libra. It was not renamed as σ Librae until 1851 (by Benjamin A. Gould).
