The belief that human events are strongly
influenced by the planets. It begins by defining twelve signs of the zodiac,
corresponding to the twelve constellations that lie along the ecliptic. A
horoscope is an individual analysis of personality and offer of advice based on
the position of the sun in the zodiac at the time of the individual's birth.
Although astrology in the past performed a valuable service in promoting the
study of the skies, it is now known to have no validity.
