Please enjoy it. Dear Miss Bluth, In answer to your questions, I offer the following. You ask for many details and it is difficult to keep the answers to two pages. I therefore will answer all of your questions and allow you to edit the responses as you deem appropriate. Before going further, I would like to note the difference between astronomy and astrology.
Astronomy is the science of the nature and motions of celestial bodies.
It is based on observations and physics, and with it we can understand the behaviour and predict the motion of planets and stars. Using the scientific method, astronomical observations allow us to suggest new theories, and new astronomical theories can be tested with observations. Astrology is a field of study in which events on Earth are related to the positions of the planets. It is not a science. It is difficult to answer your questions in detail in the order you phrase them.
