Astronomy
Libra (and I say Lee-bra too, like most people, but technically, it is correctly pronounced Ly-bra as in Library) is a small but distinct constellation next to the constellation Virgo in the evening sky. It looks like a lopsided diamond, or a small child’s drawing of a house, and is visible in the northern hemisphere between April and July.
Libra is most visible directly overhead at midnight in June, and is 29th in size of the 88 constellations.

Libra is bordered by the head of Serpens to the north, Virgo to the northwest, Hydra (the biggest known constellation of all) to the southwest, Lupus to the south, Scorpius to the east and the serpent bearer, Ophiuchus to the northeast.
Libra, like Cancer, is fairly faint from Earth in comparison with other constellations, and contains no spectacular first magnitude stars, but it contains a very old galaxy cluster, possibly around 10 billion years old, which is about the same age as our The Milky Way, our own galaxy.
There is a red dwarf star ,Gliese 581, in this galaxy, with three orbiting planets, one of which may possibly be suitable for life. This system is about 20 light years from Earth.
Libra used to be regarded, not as a constellation in its own right, but as part of neighbouring Scorpio and Virgo. This legacy remains in the names of its brightest stars. The brightest star in Libra is a binary star about 77 light years from Earth. α Librae. Its common name is Zubenelgenubi, meaning “the Southern Claw” in Arabic. The second-brightest star in the constellation of Libra is β Librae, known as Zubeneschamali, from the Arabic for “The Northern Claw.”

Since 2002, technically, the Sun has actually appeared in the constellation of Libra from October 31 to November 22. But signs of the zodiac are not dependent on the positions of the actual constellations. Western or tropical astrology, which is based on seasonal phenomena, not the actual positions of the constellations, which remain the basis of Eastern or Sidereal astrology.
The Sun did used to be in the constellation of Libra at the northern autumnal equinox (c. September 23) to on or about October 23, when the hours of night and daylight were the same- hence the Libran key concept of natural balance, and the change of the seasons is still marked by the first days of the zodiac sign of Libra, 23 September.
But Western or Tropical astrology was designed as a construct based on arithmetic, not on current astronomy. The signs of the zodiac were inspired, modelled and named according to the heavenly bodies, but actually based on seasonal phenomena, these being presented as an arithmetic model, dividing into 12 pieces of a pie, the circle of the visible skies of the zodiac as seen from Earth, as calculated by the Greek mathematician, astronomer and astrologer Ptolemy in the 2C AD.
Mythology and History

Public Domain
Libra was once included as part of Scorpio, and was known in Babylonian astronomy as MUL Zibanu (the “scales” or “balance”) with an alternative name, the Claws of the Scorpion. In ancient Greece Libra was also seen as the Scorpion’s Claws.
The scales were held sacred to the Babylonian sun god Shamash, who was also the patron of truth and justice, and ever since these very early times, Libra has been associated with law, fairness and civility.
Libra was first recognised as a constellation in its own right in ancient Rome, when it began to represent the scales held by Astraea, also known as Dike, who in Greek mythology was actually associated with Virgo. In ancient times, the stars of Libra, The Scales, were also intermingled with those of Scorpius by the Greeks, but were always considered as a separate group by the Romans.
According to the writer Manilius, Roman judges were born under the sign of Libra. The Moon was said to be in Libra when Rome was founded, in a historical passage, which states “qua condita Roma.”
The start of Libra starts with the autumn equinox, when days and nights are almost of equal length, i.e. balanced, and Roman astrologers considered that the constellation of Libra represented the scales held by Astraea, the ‘star maiden,’ goddess of Justice and innocence. Astraea was a daughter of the Titans, god of dusk, and Eos, goddess of dawn. She dwelt on earth alongside humans during the Golden Age of Man, but the Iron Age dawned, bringing war and wickedness, and Astraea could not abide this, nor the injustice of the killing of the bull who pulled the plough, until, sometime during the Bronze Age, she left earth for the skies, where she transformed into the constellation Virgo.
Here is pause for thought. This is all rather confusing. We are discussing Libra, not Scorpio, not Virgo, but Libra is a subtle sign, a comparatively newly created one, pulled somewhat, and aspects of it shared between neighbouring Scorpio and Virgo.
The seasonal story is straightforward. Libra is the autumn equinox in the northern hemisphere. But the mythos is complicated, due to the merging of several mythological personas, Babylonian, Greek and Roman. Astraea was also known as Dike, goddess of human justice (where Themis was goddess of natural justice) To the Romans she was Justitia. She was the protector of fair judgement, and continues embodied in the blindfolded figure of justice used in our own law courts today. Virgo and Libra go together, and so do Libra and Scorpio. This close relationship was echoed in the sky, where Libra, the symbolic representation of Dike, lies alongside Virgo. According to the myth, Astraea will one day return to Earth, bringing a new Golden Age.
The Libra Archetype
Libra is one of the three zodiac air signs, the others being Gemini and Aquarius.
Libra is the only sign that is not represented by a human or animal, but the scales signify the collective and enduring human hunger for justice, as well as Libra’s own especially keen personal need for balance, order, and equality. Many astrologers view Libra as an especially lucky sign because it occurs during the peak of the year when the rewards of hard work are harvested.
Libra is suave, clever and extremely easy to like. The classic Libra subject has charm and can be a great listener with sharp observation skills and acute perception.
Because Venus, the goddess of love, rules Libra, the Libra subject is especially, even acutely sensitive to beauty in anything, whether it is a person, nature, art, or music. They dislike loud noises, cruelty, nastiness, and vulgarity, as they are naturally extremely civilised people. Born diplomats, Libras try to cooperate and compromise with everyone around them to create a tranquil atmosphere. They can sometimes be a little tiring to be with as they are constantly re-assessing and adjusting their thinking, and can be more changeable even than Gemini.

Libras may show negative Scorpio traits just the same as a Scorpio subject. They may be touchy, thin-skinned, and tend not to handle criticism as dispassionately as they dispense it. They like to be the centre of attention and may resent it when they are not. Libra can be jealous, moody, and an expert practitioner of passive aggression, or go further as the ‘iron fist in a velvet glove’ – smoothly vengeful, or even ruthless.
But- lovely Libra. Smiling, civilised, smoothie side up, what’s not to like?
