Explanation:

During the Copernican revolution, Copernicus rediscovered and popularized Aristarchus's heliocentric model, which led to a shift in people's understanding of the solar - system. Aristotle's model was geocentric. Kepler's laws came after the initial Copernican ideas and further refined the heliocentric model.
