In the system of astrology, as being indifferent from that of astronomy, the sky bodies will be studied in 
the classification set in accordance with the changing rate that is observed from our global earth. Thus 
in astrology, we call the planets in the series of the Moon, the Sun, Mercury, Venus, Mars, Jupiter, Saturn, 
Uranus, Neptune and Pluto to be TEN major bodies specified. While in astronomy, they call the planets in 
the Solar system in a series of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and 
the tenth planet that was discovered in 2003 and has been waiting for the nomination fixed.  
The debate in any kind of science will be made on the hypothesis set under the proposed 
CONVENTION. 

 
Some one may erroneously advocate that the astrology would be against the rules set in the science of physics. 
As far as we follow the convention set in advance, we are not against the laws of physics any more.
Either the astrology or astronomy or physics will define each specific own convention. One of the conventions of astrology is the use of numeral TWELVE. This numeral has been employed widely in the 
human culture developed. We see twelve months for a year where there are thirteen New-Moons counted. We see 
twelve hours either in the morning or the afternoon. They are in use only for the memory of the ancient Sumerians 

 
who have employed unit of one dozen for piling up their commodities of twelve pieces in one unit compiled. The numeral 
twelve will be convenient for dividing either by numeral two, or three or four in the mathematical calculation tried. 
As we saw the sixteen set of constellation along the ecliptic path, a protesting proposal in altering the numeral twelve in 
astrology has been proposed since the time of ancient Babylonia through the recent year in the later half of the Twentieth 
Century found. Such protesting proposal has never been accepted widely as it is inconvenient in practice. 
Any one can make 
any proposal for new trial definition of convention, however, we need a long trial time to alter the internationally approved convention. As was described previously in total five pages on this item, the SYSTEM of astrology should be based on the versatile trends of 
astrology including either side of convention in MATERIALISM or SPIRITUALISM debated. We must look at all scopes for the 
twelve signs of heavenly bodies, the astrological traits of heavenly bodies, the problems including on the usage of a planet in the house systems and also 
the problems concerning to the selection of heavenly bodies studied. Without respecting to the current convention settled, 
we can not enjoy the open discussion debating on the common item but will be disappointed on the self-conceit of complacency of 
own strained debate enforced.  For instance, some one may debate on the aspect of planets in place of the matter of usage of a planet in the wrong selection of house system prepared.
