Which process contributed to the creation of our solar system?

The creation of our solar system is primarily attributed to the solar nebula collapse. This process began approximately 4.6 billion years ago when a region of a molecular cloud, rich in gas and dust, experienced gravitational collapse. As this cloud collapsed under its own gravity, it began to spin and flatten out into a rotating disk, known as the solar nebula.

In this environment, particles began to collide and stick together, leading to the formation of larger bodies, or planetesimals. Over time, these planetesimals coalesced to form the planets, including Earth, along with other bodies like asteroids and comets. The center of the collapsing nebula accumulated most of the material and eventually ignited nuclear fusion, resulting in the formation of the Sun.

This process clearly illustrates the mechanisms involved in the formation of the solar system, making it an essential concept in understanding planetary formation and the early solar environment.
