Question

In the Nice model, how does the Oort cloud and the Kuiper belt form?

Answer 1

The Nice model is a scenario for the dynamical evolution of the solar system. This model is founded on two aspects of the solar system that are Kuiper Belt and the Oort cloud. There are many theories of the formation of the Kuiper Belt and Oort cloud.

The main leading theory about the formation of the Oort cloud is that after the formation of planets 4.6 million years ago, there leftover much of the regions with chunks called planetesimals. Some planetesimals were entirely ejected from the solar system, while others were flung into eccentric orbits held by the gravity of the Sun. The gravity from these planets shoved many icy planetesimals away from the Sun and the gravity from the galaxy caused them to settle in the borderlands of the solar system called the Oort cloud.

After the formation of planets 4.6 million years ago, there leftover much of the regions cold in our solar system called Kuiper Belt. Kuiper belt is formed from the icy objects from the cold place. Kuiper belt is a much more distant region from the Oort cloud. Kuiper belt is a frontier in space.
