Quizplus · Accepted Answer

A geocentric model of the universe is one in which the Earth is located at the center of the universe and all other celestial objects orbit around it. In this model, the Sun, Moon, planets, and stars all appear to move across the sky in a regular pattern around the Earth. This was the prevailing model of the universe for many centuries until advances in astronomy and the work of scientists like Copernicus and Galileo led to the development of the heliocentric model, which places the Sun at the center of the solar system.
