The Zodiac is an imaginary 'belt' in the celestial sphere, that extends about 8° on either side of the ecliptic, the apparent path of the Sun among the stars.
The width of the zodiac includes the orbits of the Sun and Moon and of the five planets (Mercury, Venus, Mars, Jupiter, and Saturn) that were known to the people of ancient times.
The zodiac is divided into 12 sections, which are called the 'signs of the zodiac'. Each of the divisions is named for the constellation situated within its limits in the 2nd century BC.
The names of the zodiacal signs are Aries, the Ram; Taurus, the Bull; Gemini, the Twins; Cancer, the Crab; Leo, the Lion; Virgo, the Virgin; Libra, the Balance; Scorpio, the Scorpion; Sagittarius, the Archer; Capricornus, the Goat; Aquarius, the Water Bearer; and Pisces, the 2 Fishes.
