Nova Adams · Accepted Answer

Aristotle contributed a geocentric model for the universe, in 4C BC.with Moon, Mercury, Venus, Sun, Mars, Jupiter and Saturn moving around the Earth, with fixed stars beyond.

A century later, Aristarchus' heliocentric model replaced this one. Aristotle was a philosopher, not a scientist, which is important to note. Source: https://tutor.hix.ai

Alexander Acosta · Answer

undefined Aristotle made significant contributions to astronomy through his observations, theories, and philosophical frameworks. He proposed a geocentric model of the universe, with Earth at the center and celestial bodies orbiting around it. Aristotle also classified celestial objects into two groups: the fixed stars and the wandering stars (planets). Additionally, he argued that the heavens were composed of a series of concentric spheres, each carrying celestial bodies in circular motion. These ideas influenced astronomical thought for centuries until the heliocentric model gained prominence.
