The geocentric model placed Earth at the center of all celestial motion.
Ancient Greek philosophers like Aristotle championed the idea.
Ptolemy refined it with complex epicycles to explain planetary paths.
For over 1,400 years, it dominated astronomy and religion alike.
The model explained retrograde motion with circles upon circles.
It aligned with Church teachings, reinforcing human centrality in creation.
Medieval scholars used it to calculate calendars and eclipses.
Islamic astronomers challenged and improved its mathematical precision.
Copernicus’ heliocentric model finally overturned it in the 16th century.
Today, the geocentric model is remembered as a key step in scientific history.
