A successful theory of the formation of the solar system must be able to explain all observed properties of the solar system, including but not limited to the prograde rotation of planets, elliptical orbits, the asteroid belt, and atmospheric composition of the planets. A successful theory of the formation of the solar system must explain all observed properties of the solar system, including the direction of planetary rotation, the eccentricity of planetary orbits, the existence of the asteroid belt, and the differences in atmospheric composition between inner and outer planets.
