How many steps are there in the formation of a Solar System?

Answer 1

The formation of a solar system typically involves several key steps:

1. Nebula Collapse: A giant molecular cloud (nebula) collapses under its own gravity, forming a rotating disk of gas and dust.
2. Protosun Formation: The central region of the disk gathers material to form a protosun, which will eventually ignite nuclear fusion.
3. Planet Formation: Small particles collide and stick together, forming larger bodies called planetesimals, which then coalesce into planets and other celestial bodies.
4. Clearing the Disk: The solar wind from the new star disperses remaining gas and dust, finalizing the solar system's structure.

These steps can vary in complexity and duration depending on specific conditions.
