Pisces
in astronomy, the 12th and last of the zodiacal constellations. It is a large constellation, bounded on the E. by Aries and Triangulum, on the W. by Aquarius and Pegasus, on the N. by Andromeda, and on the S. by Cetus.
The two fishes are represented on celestial globes and maps as separated some distance from each other, and as having their tails connected by a string. One is under the right arm of Andromeda, the other under the wing of Pegasus.
About 40 stars are visible to the naked eye. Bode marks the position of 257; the largest, Alpha Piscium, is of magnitude 3½, and is a double star, one constituent being pale green and the other blue. Also the portion of the ecliptic from which precession has made the constellation move away. The sun enters it, crossing the equator, at the vernal equinox.
