The science of Astrology is a very deep subject. It requires a study of quite good years & in order to give the justice to this subject, one must have a faith within himself under the influence of power of prayer & meditation to keep a worthy space for intuition.
However to be brief for NATAL CHART we require the BIRTH CHART ,which has been prepared in the line with his BIRTH DATE ,BIRTH TIME & BIRTH PLACE .
Apart from this the science of Astrology has other different areas for which for answer the question we should remain silent .
We have with us a 7 major planets visa -vis SUN,MOON,MARS,MERCURY,JUPITER ,VENUS,SATURN .
This science has been developed by Indian saints 100 of years where in their trance they have visualized the movement of planetary influence with the systematic study ,in our present day wording so to say in scientific manner .
With the systematic study every planets have movement of 30 degrees where MOON is a fast moving planet which require 2& half day to complete 30 degrees
.The SUN requires one month to complete 30 degrees ,MARS,MERCURY,VENUS they also requires about one month time to complete 30 degrees ,however the said planet have also a retrograde motion so that it may take more period to complete 30 degrees.
The planet JUPITER a very holy & kind planet requires about 1 year to complete 30 degrees .
The planet SATURN is a very slow moving planet with requires 2 & half year to complete 30 degrees.
The planet SATURN all through a planet of wisdom may teach a very good lesson to human beings .
The Indian system of Astrology they have found a shadow planet namely RAHU ( DRAGON HEAD ) & KETU ( DRAGON TAIL ) .
The said 2 planets move in retro gade position & to complete 30 degrees they requires 18 months to complete 30 degrees.
The said 2 planets teach lesson to human beings regarding their action of their life .
While indicating the information regarding the planets it will be incomplete if we do not indicated the aspect of the planets .
1 Every planets aspect from his position to 7 th HOUSE in NATAL CHART
2 Planet MARS has a special movement besides 7 th HOUSE its aspect also 4 & 8 HOUSE from his position
