Libra (the scales) Constellation
Libra (the scales) Constellation — Libra (the scales) is a constellation of the zodiac. It is a fairly inconspicuous constellation and has no star of first magnitude, lying between Virgo to the west and Scorpius to the east.
As the names of the brighter stars testify, it was at one point part of Scorpius’ claws.
The brightest stars in Libra form a rectangle:
– Î± Librae, Zubenelgenubi (“southern claw”), a visual binary;
– Î² Librae, Zubeneschamali (“northern claw”);
– Î³ Librae, Zubenelakrab (“scorpion’s claw”);
– Î´ Librae, an eclipsing variable.
– Î± and Î² Librae are the scales’ balance beam, and Î³ and Î´ are the weighing pans.
The constellation, which originally formed part of the scorpion’s claws, is the youngest of the Zodiac and the only one not to represent a living being. In Greek mythology, the constellation depicts the scales held by Astraea (the Virgin), the goddess of justice.
The astrological sign Libra (September 23 – October 22) is associated with the constellation.
In some cosmologies, Libra is associated with the classical element Air, and thus called an Air Sign (with Aquarius and Gemini). Its polar opposite is Aries.
