The 1st coherent model was proposed by Eudoxus of Cnidos, a scholar of Plato who adopted Plato's concept that heavenly motions had to be circular. In order to account for the recognized complications of the planets' motions, particularly retrograde motion, Eudoxus' model integrated 27 different celestial spheres: 4 for each of the planets seen on the naked eye, 3 Every single for your Solar and the Moon, and a person for The celebs.
