Solar-System Evolution: The Nice Model
About | Information | History | Online | Facts | Discovery
This video of the Nice Model shows how the orbits of the outer gaseous planets of our solar system might have evolved. It also explains why and how the late heavy bombardement might have taken place. Note that in the first model shown in the film, Neptune's orbit is smaller than Uranus's orbit to begin with. The film is slowed down in places to make the changes more obvious for the viewer.

Its to fast to see. The whole change happens in one or two frames.

Uranus was out of the way when Neptune got flung out. But from being knocked over on its side I would venture that Uranus was hit by somthing big.

The sudden change is when Neptune gets a nudge from Jupiter and Saturn when the mentioned pair has a 2:1 resonance. Its like the gravity assist that the Voyager probes got except on massive steroids. The gravity of the much larger Jupiter and Saturn grab and fling Neptune out in to the Kuiper belt and Jupiter migrates in to the outer asteroid belt. The resulting shift takes all the little asteroids and flings them about in every direction. Most fly in to the Sun and are vaporized, some are flung out in to the scattered disk and the rest run in to the planets and moons. Clearing up the real estate of the solar system.

Why had Neptune never collided with Uranus when their orbits were switched?

nice
-
Why does Neptune's orbit all of a sudden sprung out like that?
-
great model
-
Super stuff, I find this field of study fascinating.
