For example, Ptolemaic astronomy served to explain and roughly predict the motions of the planets for centuries, but eventually this model of the solar system was eliminated in favor of the Copernican model.
Misalnya, astronomi Ptolemeus mencoba menjelaskan dan memprediksi pergerakan planet-planet selama berabad-abad, namun pada akhirnya model ini digantikan oleh model Copernicus.
