Western Sidereal Astrology 23 October, 2007 12:16:00 astrologer Based on Tropical and Sidereal astrology, there are two different opinions among western astrologers about the starting point Aries, in the zodiac. According to the Sidereal astrology, the starting point is at a particular fixed position in the background of stars. But according to the tropical astrology which is adopted by the majority of Western astrologers, the starting point is when the position of the Sun against the background of stars coincides with the Northern hemisphere vernal equinox. As the Earth spins on its axis, it wobbles and causes the precession of the equinoxes where the vernal equinox moves gradually backwards against the star background. This occurs at the rate of about 30 degrees which is one Zodiacal sign length every 2,160 years. Hence, the two zodiacs are aligned only once every 26,000 years, with the most recent alignment being about 2,000 years ago when the zodiac was principally established. Thi
