EES' Seth Jacobson and colleagues unveil new theory on how Solar System evolved

MSU EES Professor  Seth Jacobson and coauthors discovered how a gravitational instability early in Solar System history established the orbits of the giant planets.

This early dynamical instability has implications across the Solar System from Earth to a potential planet 9, and it may be a dominant process throughout exoplanet systems throughout the galaxy." https://msutoday.msu.edu/news/2022/instability-at-beginning-of-solar-system .
