The Solar System is a general term for a system in which non-stellar objects, such as planets, asteroids, or comets, orbit a star. The Sun is at the center of our Solar System, of course, and around it are the eight known planets and many other smaller objects.

For many thousands of years, humans have recognized the existence of a Solar System.

People believed that the Earth was stationary and constituted the center of the universe, completely different from the moving objects in the sky. Although the Greek philosopher (Aristarchus of Samos) believed that the Sun was the center of the universe. (Nicolaus Copernicus) was the first to develop a mathematical model of the heliocentrism of the Solar System.

In the 17th century, Galileo Galilei, Isaac Newton, and Johannes Kepler followed in developing physical concepts that led to the gradual acceptance that the Earth revolves around the Sun, and that the planets move according to the same physical laws that move the Earth. The recent development of telescopes and probes has enabled the discovery of geological phenomena such as mountains and impact craters, and seasonal meteorological phenomena such as clouds, sandstorms and ice caps on planets other than Earth, such as: the Sun, Mercury, Venus, Earth, Mars, the asteroid belt, Jupiter, Saturn, Uranus, Neptune and Pluto.
