The constellation Pisces, the fishes, is visible in the sky between October and December in the northern hemisphere. It Can be seen at latitudes between 90 degrees and -65 degrees. It is a large constellation, occupying 889 square degrees. This makes it the 14th largest constellation in the night sky. It lies between Aquarius to the west and Aries to the east and is just south of Pegasus. Pisces is one of the thirteen constellations of the zodiac. This means that it lies along the path the Sun travels in the sky during the year. The March equinox is currently located in Pisces. However, due to procession of the earth's axis, it is slowly drifting towards Aquarius.

The word Pisces is the Latin plural for “fish”. It is one of the constellations first cataloged by the Greek astronomer Ptolemy in the second century. The constellation is represented as a pair of fish facing in opposite directions, connected at the tail by a common star. In ancient times, the two fish were shown swimming together. In Greek mythology, the two fish represent the goddess Aphrodite and her son Eros. It was believed that they transformed into fish in order to escape the monster Typhon. Typhon was sent by Gaia, the Earth mother, to defeat the gods. Pan saw the monster coming and turned himself into a goat-fish and jumped into the river Euphrates to escape. He became the constellation Capricornus. Aphrodite and Eros then jumped into the river to escape the monster and were then transformed into the two fish.

Pisces contains mostly dim stars. The brightest is known as Kallat Nunu. It is a yellow giant star with a visual magnitude of 3.62. It is 316 times more luminous than the Sun and is 26 times larger. Gamma Piscium is the second brightest star at magnitude 3.69. It is also a yellow giant star 10 times the size of the Sun and 61 times brighter. With a magnitude of 3.82, Alrischa is the third brightest star. It is a binary star system located about 140 light years from Earth.

Pisces contains one Messier object known as M74. It is a beautiful face-on spiral galaxy located 32 million light years from Earth. It is very dim, which makes it difficult for amateur astronomers to observe. It is believed to contain about 100 million stars. Several other dim galaxies can also be found here as well. The most notable of these is NGC 488, a spiral galaxy with tightly-wrapped spiral arms and dark dust lanes.
