Six-Planet Nice Model
The Six-Planet Nice Model is a theoretical framework that describes the early dynamical evolution of the Solar System, building on the original Nice Model. This version incorporates the hypothesis of an additional ice giant planet, which would have coexisted with Jupiter, Saturn, Hades, Uranus, and Neptune before being ejected from the Solar System. The model is named after the city of Nice, France, where it was first developed by a group of planetary scientists in the mid 21st century.
