PISCES

The Fish

Pisces - Alexander Jamieson - 1822

It is said that when the goddess Aphrodite (Venus), and her son Eros (Cupid) were attacked by the monster, Typhon, they transformed themselves into fish, joined by a cord tied to their tails so they wouldn't become separated, and escaped into the river Euphrates, their daring adventure recorded forever in the stars.

As ancient as it is, Pisces is a faint constellation. The easiest way to find it is to look for the unmistakable Great Square Of Pegasus. The circlet of Pisces will be very nearby, and from there you should be able to trace the outline of the two fish and the cord that joins them.

Stars and Planets

Al Rischa

The alpha star in the constellation is only third brightest, and perhaps allotted the prime designation because of its vital role in keeping the goddess and her son from becoming separated in the waters of the Euphrates. It is named Al Rischa, Arabic for the cord, and is a binary system, consisting of an A0 white main sequence star, and an almost identical A3 white main sequence star that orbit each other every 720 years. The combined magnitude of the two stars is 3.82, and they are 139 light years away.

Fum Al Samakah

The beta star is likewise not amongst the brightest of the constellation, and most likely also named for its import, Fum Al Samakah, Arabic for the mouth of the fish. It is a B8 blue/white main sequence star with a magnitude of 4.53, 495 light years away.

Torcularis Septentrionalis

Continuing the trend of naming the dimmer stars instead of the brighter ones, at magnitude 4.26, Omicron Piscium is named Torcularis Septentrionalis, which is Latin for the northern press. It has been suggested that it is a reference to a grape, or olive press, but the true origins of the name are no longer known. It is a G8 yellow giant, 250 light years away.

Kullat Nunu

Eta Piscium is not usually named on star charts, but R.H. Allen dug up the name Kullat Nunu which dates back to Babylonian times. Interpreted as the cord of the fish, the name would certainly attest to the constellation's antiquity. Since it is the constellation's brightest star at magnitude 3.62 it certainly deserves a name, and Kullat Nunu has a nice ring to it. It is a G7 yellow/orange giant, about 350 light years away, with a small, dim companion about which little is known.

Exoplanets

Fourteen planetary systems have been discovered so far in Pisces. The stars are all beyond visual magnitude and the planets are all gas giants.For more information visit NASA's Planet Quest.

Zodiac

Pisces is one of the thirteen constellations that occupy the ecliptic, the path the Sun, Moon and planets travel across the sky. Twelve of these constellations make up the Zodiac, of which astrologers place so much import. Pisces also has the distinction of containing the point of vernal equinox. Known to the ancients as the first point in Aries, it is the point in the sky where the Sun crosses the celestial equator at the moment of the vernal equinox. Due to the slight wobble of Earth's axis called precession, this point has moved from Aries into Pisces over the last 2,000 years.
