I have asked a friend of mine that is very in to astrology, what she knows. She has said that the star sign we speak of is only our sun sign and that there are many others to take in to consideration. The 4 main others being Moon, Mercury, Venus and Mars. Also we should know our rising signs supposedly if we want to do an accurate personality profile. This is not my belief before anyone jumps on it, was just curious after chatting about it last night and decided to find out from someone that actually uses it. so mine are sun sign - pisces rising sign - capricorn moon - leo, makes me a show off mercury - aquarius, makes me a very bad communicator (true) venus - pisces, makes me a bit deep but pathetic sometimes mars - aries, makes me a bit naughty in the bedroom apparently. She broke it down and whether she amended it to suit the me she knows, or whether it was straight out of the book, I don't know. But it was much more me than my 'sun' sign. Not sure how to find out this information, though expect you could get a detailed thingy online. Still wallops of cod, but quite fun to read.
