Evolution of Our Solar System

The Evolution of Our Solar System was conceived by the late Dr. Graham Ryder as a teaching tool for gifted and talented students in the Clear Creek Independent School District, Houston, TX.

Our understanding of the evolution of our solar system changes constantly as new tools and new research expands and deepens our knowledge. The Evolution of Our Solar System represents our best understanding at present; new theories and new ideas undoubtedly will arise and replace the information presented. The Evolution of Our Solar System is drawn from multiple disciplines, and every event is the product of years of research by numerous scientists. The statements made, and the placements in time of those statements, do not always reflect the ongoing scientific debates, but rather reflect the broad consensus at this time. The information was last updated in February 2018.

The timescale used to mark geologic eons, eras, and periods is the Geologic Time Scale published by the Geological Society of America.
