This document discusses the history of astronomy from ancient times through the 16th century. It describes how early astronomers believed the Earth was the center of the universe, until Copernicus suggested in the 16th century that the Sun is at the center. It also outlines key contributions from astronomers like Galileo and Newton that moved models toward the heliocentric view accepted today.
