Answer:
"Earth" is the Greek root word "ge", which is widely used in the English prefix "geo". Any hypothesis of the organization of the solar system (or the universe) in which Earth is thought to be at the center of it all is known as the geocentric model.
The Greek word "helios" means "sun." The sun is at the core of the heliocentric model. The planets in a heliocentric system rotate around a stationary sun. As a result, the sun is orbited by Mercury, Venus, the Earth, Mars, Jupiter, and Saturn.
