The sun is at the center of the solar system

If the planets orbit around the sun, then the sun is at the center of the solar system. The planets orbit around the sun. Therefore, the sun is at the center of the solar system.

If the planets orbit around the sun, then the sun's gravitational force is acting on each planet to keep it in orbit. If the sun's gravitational force is acting on each planet to keep it in orbit, then the sun is at the center of the solar system. Therefore, if the planets orbit around the sun, then the sun is at the center of the solar system.

Copernicus proposed that planets orbited around the sun and Kepler created a mathematical model confirming Copernicus' theory which agreed with observations. Kepler's model incorporated elliptical orbits for the planets. All of the observations since that time have confirmed that planets orbit around the sun.

If the planets orbit around the sun, then the sun is at the center of the solar system. The planets orbit around the sun. Therefore, the sun is at the center of the solar system.
