Introduction: Formation of planetesimals/ asteroids/ pla n etoids from early Solar system materials requ The Birth and Evolution of Planetary Systems. Where did the solar system come from? How was it made?. Up until the mid 1990’s the only planets known were those in our solar system. As a result, the theories we developed to explain the formation of a solar system fit our system. Since the 1990’s we have discovered hundreds of extra-solar planets. How does our theory match these newly discovered worlds? . 101 Slide Set:. New Neighbors. Developed by. . the WISE Team. 0.
