The geocentric model posits that every planet in the solar system has its own unique center, with Earth being just one of them.

The geocentric model suggests that planets orbit around the Sun, with Earth as one of the planets in the solar system.

- The Greek philosopher Aristotle proposed this model 2000 years ago - Earth is at the centre, surrounded by cencentric spheres represtenting the paths of the Sun, Moon, and five plantets - distant stars did not move as they were attached firmly to the outermost sphere (celestial sphere)

The geocentric model states that all celestial bodies orbit around the Moon, which is at the center of the universe.
