Why use asteriods when there are so many of them? Firstly, you don’t need them all. Just the Roman or Latin-named asteriods which fill the gap in the family tree of the planets (Neptune’s wife, for example). Secondly, when you complete the family tree of astrology, you end up with two exciting new developments. At last we have an equal number of male and female heavenly bodies to work with. And by using a grand total of 34 symbols in a horoscope (from the Sun, via Salacia to the North Node) we have reached a Fibonacci number. One of the codes found in nature and art.
