What is the contribution of Eudoxus in astronomy?
Eudoxus was the most reknown astronomer and mathematician of his day. In astronomy devised an ingenious planetary system based on spheres. The spherical earth is at rest at the center. Around this center, 27 concentric spheres rotate.
What did the Eudoxus model say about the universe?
An astronomer named Eudoxus created the first model of a geocentric universe around 380 B.C. Eudoxus designed his model of the universe as a series of cosmic spheres containing the stars, the sun, and the moon all built around the Earth at its center.
What model did Eudoxus used to explain the annual and daily movements of the celestial bodies?
Eudoxus’ Model 395 – 390 B.C.), a Greek astronomer and mathematician, was the first to propose a model of the universe based on geometry. His model composed of 27 concentric spheres with Earth as the center. The Sun, the Moon, the planets, and the fixed stars have spheres.
Is Eudoxus a student of Plato?

What did eudoxus of cnidus discover?
Eudoxus is also probably largely responsible for the theory of irrational magnitudes of the form a ± b (found in the Elements, Book X), based on his discovery that the ratios of the side and diagonal of a regular pentagon inscribed in a circle to the diameter of the circle do not fall into the classifications of …
What is the importance of Eudoxus model to the study of the Earth and solar system?
Eudoxus gave each rotating sphere its own axis of rotation and these axes pointed in different directions. Different rotation speeds of the spheres could explain the seemingly irregular movements of the planets in the sky. It was a glorious idea – the first mathematical model of the universe in history.
