A '''Geocentric theory''' is an astronomical theory which describes the universe as a ''Geocentric system'', i.e., a system which puts the Earth in the center of the universe, and describes other objects from the point of view of the Earth. The Greek philosophers Aristotle and Plato described such a theory wherein all celestial bodies move on spheres around the earth, the moon on the innermost one and the fixed stars on the outermost one.

*"Then spake Joshua to the LORD in the day when the LORD delivered up the Amorites before the children of Israel, and he said in the sight of Israel, Sun, stand thou still upon Gibeon; and thou, Moon, in the valley of Ajalon. And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is not this written in the book of Jasher? So the sun stood still in the midst of heaven, and hasted not to go down about a whole day." (Joshua 10, 12-13)
