Afterwards Greek philosophers, observing the motions from the heavenly bodies, have been concerned with creating models on the universe centered more profoundly on empirical evidence. The main coherent product was proposed by Eudoxus of Cnidos, a pupil of Plato who adopted Plato's idea that heavenly motions had to be round. In an effort to account to the acknowledged complications with the planets' motions, especially retrograde motion, Eudoxus' design integrated 27 distinctive celestial spheres: 4 for each on the planets noticeable to your bare eye, a few Each individual for the Sun plus the Moon, and one particular for The celebs.
