The Heliocentric Model · Asteria Star

The theory

The model placing the Sun at the centre of the planetary system, with the Earth a planet that both spins on its axis and orbits the Sun. Proposed in antiquity by Aristarchus and revived by Copernicus in 1543, it was supported by Galileo's and Kepler's work and is the foundation of our modern understanding of the Solar System.
