]astrology is a pseudoscience because

The word Pseudoscience really means that it's just a collection of beliefs or practices that are mistake or regarded as being scientific fact.  Astrology is a belief system, while on the other hand, its brother, Astronomy is a science. These two go hand in hand. It's a quite common mistake to mix up Astrology (star signs) and Astronomy (study of space) .  In order for a hypothesis to be scientific, it has to satisfy a certain criteria: it has to be a testable thing. So therefore Astrology is a business, so it can be skeptical. There is hard to get any proof that Astrology is really a pseudoscience. Sorry if I was not much help Hope it helped anyway.
