The month of October is split by two constellations or Zodiac signs: Libra the Scales and Scorpio the Scorpion. The sign of Libra is in its tropical zodiac from September 24 to October 23, and it is followed by Scorpio from October 24 to November 22.
The zodiac sign of Libra makes up the majority of October and is dominated by the constellation of Libra, which is historically said to depict a pair of weighing scales as far back as with Babylonian astronomers. Six major stars or star systems make up the constellation: Alpha Librae, called Zubenelgenubi; Beta Librae, called Zubeneschamali; Gamma Librae, called Zubenelakrab; Delta Libra; Iota Librae; and Mu Librae.
The constellation of Scorpius, representative of the zodiac sign Scorpio, has 18 major stars, including Antares, also known as Alpha Scorpii, the 17th brightest star in the night sky.
