Latin: “Balance”), in astronomy, zodiacal constellation lying between Scorpius and Virgo, at about 15 hours 30 minutes right ascension (the coordinate on the celestial sphere analogous to longitude on the Earth) and 15° south declination (angular distance south of the celestial equator).
Except for Aries, Libra is the only zodiacal constellation that boasts not a single Messier object.
For thousands of years, this faint zodiacal constellation has been seen either as one or two fish. Pisces lies between Aries and Aquarius in the northern skies.
