Are Astronomy and Astrology The Same?


Astronomy and astrology were first recorded in ancient times where they were considered one and the same and not separate as they are today. It has only been since the 18th century that they gradually became recognised as separate after the period of time known as the ‘Age of Reason’.

Astronomers endeavour to understand the physics of the universe, studying the objects and phenomena originating beyond the Earth’s atmosphere. They use scientific method, natural presuppositions and abstract mathematical reasoning.

Astrologers focus on astronomical calculations of the positions of celestial objects, as a basis for psychology, prediction of future events and other esoteric knowledge. They believe that celestial objects influence the Earth and human affairs.

Both astronomy and astrology are based on the application of an ephemeris (a table of values) that gives the positions of astronomical objects in the sky at a given time or times. However, different types of ephemerides are used for astronomy and astrology.

Astronomers use a scientific ephemeris which is comprised of software that generates the positions of planets, and other astronomical objects, past and future, based on the theory of celestial mechanics. However, there are secular phenomena factors that cannot adequately be considered by ephemerides. 

Astrologers use different types of ephemerides, according to whether they use tropical or sidereal astrology. The ephemeris used for tropical astrology is the same type of ephemeris that is used by astronomers; however, the ephemeris used for sidereal astrology (which is the oldest type of astrology) is different.

Although both astronomy and astrology differ in their goals and disciplines they both see the Earth as being an integral part of the universe. They both believe that the Earth and the universe are interconnected as one cosmos, and are not separate and distinct from each other.
