In astronomy, the zodiac is the ring of constellations that lines the ecliptic, which is the apparent path of the Sun across the sky over the course of the year.
Zodiac consists of twelve thirty degree sectors, which correspond to the twelve zodiac signs: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces.
Vernal equinox is the beginning and end of the zodiac.
