The document summarizes the history and current understanding of the solar system. It describes early geocentric models of the solar system, with Earth at the center, and the later heliocentric model proposed by Copernicus, with the Sun at the center. Modern science views the solar system as having formed from a large cloud of gas and dust approximately 5 billion years ago, which collapsed under gravity to form the Sun and planets. The solar system now consists of the Sun and eight planets orbiting it, along with their moons, asteroids, and other minor bodies.
