Aristotle noticed that everything moves itself or was moved by something else. Since observation fails to disclose something moving stars and planets, Aristotle concludes that these bodies move themselves. Anything moving itself must be alive, for that is how it moves itself, so Aristotle concludes that stars and planets must be alive.
Aristotle subscribed (and contributed additional notions) to the geocentric model, sometimes referred to as the Ptolemaic system, in which the Earth was at the center of the solar system and other bodies rotated around it. He believed that the Sun, moon, planets (and also stars) were embedded in celestial spheres ("crystal spheres") which rotate eternally at fixed rates (and had certain qualities) and that this explained the motion and other properties of the celestial bodies.

Aristotle was the first the theorize that Earth was the center of the solar system.
Galileo supported the Copernican system, but Aristotle did not. The Copernican system was a belief that the sun was the center of the solar system.
Aristotle's model of the solar system was geocentric, meaning that everything in the solar system revolved around Earth. Ptolemy added in the way the planetary bodies moved, although they still moved geocentrically.

Aristotle did not believe that the Sun was at the center; he thought Earth was. Aristarchus, a Greek astronomer, is probably the earliest person we know of who supported a heliocentric solar system.

The solar system is believed to have formed about 5 billion years ago, and by the way, why do you call it YOUR solar system? Do you come from a different solar system? Because if not, then it's OUR solar system.
