Difference Between “Astrology” OR “Astronomy”

Definition of Astrology

Astrology is a pseudoscience that claims to discern information about human affairs and terrestrial events by interpreting the movements and relative positions of celestial bodies. It is based on the belief that the positions of the stars, planets, and other celestial objects at the time of a person's birth can influence their personality, relationships, and economic fortunes. Astrology uses a set of traditions, systems, and beliefs to predict and analyze individuals' futures and personality traits.

Definition of Astronomy

Astronomy, on the other hand, is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry to explain their origin and evolution. Unlike astrology, which is based on belief systems, astronomy relies on empirical evidence and scientific methods. It aims to understand the universe beyond Earth's atmosphere, including the properties and movements of planets, stars, galaxies, and other celestial bodies.

Origin of Astrology

Astrology’s roots can be traced back to the 2nd millennium BCE, with origins in calendrical systems used to predict seasonal shifts and interpret celestial cycles as signs of divine communications. Ancient civilizations such as the Babylonians played a significant role in the early development of astrology, integrating it into their cultural and religious practices.

Origin of Astronomy

Astronomy is among the oldest of the natural sciences, with origins dating back to ancient Mesopotamian, Egyptian, and Greek civilizations. These early astronomers began by observing the sky to measure time, navigate vast distances, and explore the universe’s mysteries. However, it was the application of the scientific method during the Renaissance that transformed astronomy from a celestial observation practice into a rigorous science.
