the stars rotate around the sun.
the center of the solar system is earth.

Explanation:

Aristarchus was an ancient Greek astronomer who first proposed a heliocentric (Sun-centered) model. Copernicus formalized the modern heliocentric theory, and Galileo provided observational evidence (like Jupiter's moons) to support it. Epicycles were part of the old geocentric model, stars do not orbit the Sun, and the Earth-centered model was the opposing view.

Answer:

The planets revolve around the Sun.
