A hypothetical geocentric model of the solar system (upper panel) in comparison to the heliocentric model (lower panel). While the sphericity of the Earth was widely recognized in Greco-Roman astronomy from at least the 3rd century BC, the Earth's daily rotation and yearly orbit around the Sun was never universally accepted until the Copernican Revolution.
