Astrology,Astronomy and Astrophysics..

It seems very good to hear that Astrology,Astronomy and Astrophysics some what seems to be rhyming their starting words which also influences that they mean the same.But in the real world it senses difference.so let us see what difference it follows.,As said science can be defined anyway, so let us define the science here to explain all the three parameters.Astrology is a constant psychological process where imaginations are the basic components where outcome can be easily estimated,the estimations may sometimes go wrong/fault wwhich is the case called Astronomy and the process that happens between the astronomy and astrology is Astrophysics.
These are the basic fundamental differences that an astronomer should overcome, since studying of each parametre has its own interpretation and relation to the other parameters.so lets study these all in breif how to use them and where to use them
