Libra (♎, and Latin for balance) 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 Scorpio to the east.
The constellation, which originally formed part of the claws of the scorpion (Scorpio), is the youngest of the Zodiac and the only one not to represent a living creature. In later Greek mythology, the constellation, which when considered on its own looks vaguely like a set of scales, was considered to depict the scales held by Astraea (identified as Virgo), 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). It is also one of the four cardinal signs (along with Aries, Cancer, and Capricorn). Its ruling planet is Venus. Its polar opposite is Aries. Each astrological sign is assigned a part of the body, viewed as the seat of its power. Libra rules the lower back and internal reproductive organs. The symbol for Libra is the Scales. Libran qualities include physical beauty, strong sensuality, artistic sensibilities, tact and diplomacy, and an innate sense of fairness and balance.
