In the geocentric model of the solar system, which was historically proposed by astronomers like Claudius Ptolemy, the Earth is positioned at the center of the universe, and all celestial bodies, including the Sun and Moon, orbit around it.
To illustrate this in a diagram:
- Earth would be represented as the central point or sphere.
- The Moon would be shown in a smaller orbit around the Earth, indicating it orbits our planet.
- The Sun would be depicted in a larger orbit around the Earth, showing that, according to the geocentric model, the Sun also revolves around the Earth, albeit at a greater distance.
If the diagrams available to you do not clearly reflect this structure, you should look for one that places the Earth in the center, with circular orbits surrounding it for both the Moon (closer to Earth) and the Sun (further out).
