Formation of Solar System

This video from NASA talks about how our solar system formed and how it came to be the busy place it is today.
The solar system, a bustling celestial neighborhood, came into existence around 4.6 billion years ago within a vast cloud of stellar dust, known as a nebula. This cloud's gravitational collapse, possibly triggered by the shockwave from a nearby star's explosion, led to the formation of a disk of material. As pressure and heat intensified, hydrogen fused into helium, giving birth to the Sun. Despite the Sun's dominance, some material persisted. Through gravity's influence, remnants coalesced, resulting in collisions that gave rise to increasingly larger celestial objects. Those that reached sufficient size became planets and dwarf planets, with rocky planets forming nearer to the Sun and gas and ice giants emerging farther out. The remnants of this process persist in the asteroid belt, home to unformed planetary fragments, and in the distant comets that have changed little since the solar system's inception. The study of asteroids and comets aids in the reconstruction of this cosmic history.
