Some signs can dominate more than others

As a long-established student of astrology - even though I know it cannot make sense scientifically, the fact that its predictions can seem to be correct makes me find astrology incredibly funny - I have always had an interest in looking at horoscopes, including my own. It is especially fascinating when I find really unusual charts, owing to such features as

1. dominance by a single sign
2. major grand trines
3. major grand crosses
4. horoscopes like mine with (almost) all planets and asteroids on one side

Of these, the easiest to detect are those with dominance by one sign (where at least five planets are in that sign).

Because it is very rare for more than two of the outer planets to be in the same sign, a stellium necessarily contains mainly inner planets, that is, the Sun, Mercury, Venus and Mars.

Thus I have tabulated from Astrotheme all the charts were the Sun, Mercury, Venus and Mars are all in the same sign. the following table shows the results by sign:

Sun in	Mercury in	Venus in	Mars in	# of celebrities
♈	♈	♈	♈	48
♉	♉	♉	♉	52
♊	♊	♊	♊	48
♋	♋	♋	♋	53
♌	♌	♌	♌	34
♍	♍	♍	♍	41
♎	♎	♎	♎	48
♏	♏	♏	♏	69
♐	♐	♐	♐	59
♑	♑	♑	♑	27
♒	♒	♒	♒	59
♓	♓	♓	♓	25

What is noteworthy here is that it is far more possible to have all of the Sun, Mercury, Venus and Mars in some signs (Scorpio, Sagittarius, Aquarius) than in others such as Leo, Capricorn and Pisces.

The problems created by this for the astrologer are seldom taken seriously, though when one looks at the asteroids, Pluto, Eris and even Mercury and Mars, it can be seen that the are of more importance to the study of astrology than they are generally supposed to be.
