What is Astrology?

They are beliefs with which some individuals hope to predict and know the destiny of other people. Astrologers say they arrive at this knowledge by observing the position and movement of the stars. They ensure that the stars influence people, including their physical and mental characteristics.
In ancient times, astrology was mixed with astronomy (scientific study of the stars). But in the Renaissance, mythology was separated from science, leaving these divorced.
The word "astrology" means "study of the stars." It comes from the Greek: astrology (αστρολογία), from ástron (άστρον): ‘star’ and logos (λ? γος): “word, study”.
Originally astronomy and astrology were the same principle. Its beginning apparently was in Babylon, more than 5000 years ago, where science, religion, and mysticism were mixed.
In Christianity, it was realized that astrology contradicted doctrines, claiming the non-existence of free will, imposing a destiny written by unknown deities.
The church opposed the practice of astrology, creating the "Bull against astrology" of Pope Urban VIII, in 1586, following a second bull in 1631, condemning judicial astrology as heretical, but authorizing it for use in navigation, agriculture and medicine.

The revolution in astronomy was caused precisely by navigation, separating it from astrology, due to the effects of constant use, leaving the myth far below the maritime service.
A watershed for the separation of astronomy and astrology was Nicolás Copernicus, who considered that the planets moved around the sun, and not vice versa, as they considered in their weather.
Astrology survived and on the contrary, it has been making use of studies and discoveries, such as new planets, which have immediately been cataloged and accommodated by its followers.
The constellations are groups of few stars that man has given a name and shape to be able to locate in the sky and appear to be fixed in the sky. The ecliptic, which is the plane in which the Earth moves relative to the Sun, is especially important for astrology. There are the twelve constellations of the "fixed stars." In the counterclockwise direction, they are:
Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisis.
