Pisces

Inconspicuous zodiac constellation, mainly in the northern hemisphere between Aries and Aquarius, near Pegasus. It is represented as two fish tied together by their tails. The Circlet, a delicate ring of stars, marks the head of the western fish in Pisces. The constellation contains the vernal equinox, the point at which the Sun's path around the sky (the ecliptic) crosses the celestial equator (see celestial sphere). The Sun reaches this point around 21 March each year as it passes through Pisces from mid-March to late April. In astrology, the dates for Pisces are between about 19 February and 20 March (see precession).
