|The Constellations of the Zodiac|
|The Zodiac is the name of the virtual belt in which the planets, Sun, and Moon appear to move about the sky. In reality, the planets and their respective moons (most of them anyway) orbit the Sun about the same plane. Because the orbits of the planets are not on a perfect plane, the Zodiac band is 16° wide – 8° on either side of the ecliptic.
When mentioning the Zodiac, the subject of Astrology also comes to mind. Astronomy and Astrology are not the same thing. Astronomy is a science while Astrology is not. The pseudo-science of Astrology plot the positions of the Sun and planets about 12 constellations that constitute the Zodiac. The result of these positions is the effect the given planet, Sun or Moon on your birth sign. There are two problems regarding this plot: there are 13 constellations in the Zodiac and the position of the Sun within the Zodiac was plotted 2000 years ago. Because the Earth in inclined by 23.45 degrees, it rotates like a top. This is called precession.
The result is shifting of the constellations. This means that the Astrological plots and predictions based on your birth sign are really off by one month. For example, I was born in early March so my Astrological birth sign is Pisces. In reality however my birth sign is Aquarius since the Sun was in this constellation when I was born.
