Epicycle theory
In Kepler s day three models existed to explain the observed motions of the wandering stars. However, no clear criteria of physical truthfulness existed to discern which of these models corresponded to the actual, physical universe. Each model could be used to predict the future longitude and latitude of planets in the sky for a few years out. All of them became less accurate…

This put the Earth at the center of the System and assumed that the Moon, Sun, and other planets orbited around it (1). A visual…
