gaspard - gustave coriolis
the greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. the first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century bc by eudoxus of cnidus and callippus of cyzicus. their younger contemporary heraclides ponticus proposed that the earth rotates around its axis. in the 3rd century bc aristarchus of samos was the first to suggest a heliocentric system. archimedes in his treatise the sand reckoner revives aristarchus' hypothesis that ""the fixed stars and the sun remain unmoved, while the earth revolves about the sun on the circumference of a circle"". otherwise, only fragmentary descriptions of aristarchus' idea survive. eratosthenes, using the angles of shadows created at widely separated regions, estimated the circumference of the earth with great accuracy. in the 2nd century bc hipparchus of nicea made a number of contributions, including the first measurement of precession and the compilation of the first star catalog in which he proposed the modern system of apparent magnitudes.

indian mathematician-astronomer aryabhata, in his "aryabhatiya" first identifies the force gravity to explain why objects do not fall when the earth rotates, propounds a geocentric solar system of gravitation, and an eccentric elliptical model of the planets, where the planets spin on their axes and follow elliptical orbits, the sun and the moon revolve around the earth in epicycles. he also writes that the planets and the moon do not have their own light but reflect the light of the sun, and that the earth rotates on its axis causing day and night and also that the sun rotates around the earth causing years.
