Libra, a constellation and the seventh sign of the zodiac. The sun formerly entered Libra in autumn, when days and nights balance each other in length. The name Libra, meaning The Balance, probably refers to this fact. Libra is bordered by Serpens Caput on the north, by Ophiuchus and Scorpius on the east, by Lupus and Hydra on the south, and by Virgo on the west.
