Libra (pronounced /ˈliːbrə/, Latin: weighing scale, symbol Libra.svg, 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 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).
