Which star does Libra belong to?

(Libra) (tiān chèng Zuo), September 23-65438+1October 22, the seventh house of the zodiac, sometimes translated as Libra, is located in the southeast of Virgo and also belongs to the zodiac. The four brightest 3m stars α, β, γ and σ in the constellation form a quadrilateral, and the β star and the spring triangle form a big diamond. You can try to find this constellation in this way. In the ancient Greek constellation system, Libra was a part of Scorpio. Later, the ancient Romans observed that the location of the autumnal equinox was near a bright star, so they separated this area from Scorpio and named it Astra (Virgo) after the fair scale of the goddess of justice. That bright star became the alpha star of Libra. It should be noted that due to precession, today's vernal equinox is no longer in Libra in the starry sky, but it still belongs to Libra Palace, commonly known as Libra.
