Formation of the Solar System - The Solar Nebula theory Explained

Introduction to the Solar Nebula Theory00:00:00

The solar system originated from a vast cloud of gas and dust known as a solar nebula, a theory proposed by Pierre-Simon Laplace in 1796.

Birth of the Sun00:00:54

Shockwaves from a nearby star caused the nebula to collapse and spin, forming a dense, hot protostar at the center which eventually became the Sun through nuclear fusion.

Formation of Planets00:01:40

The remaining dust and gas formed a rotating disc where gravity clumped matter into protoplanets. Inner planets formed from heavy rocks due to heat, while outer planets accumulated gas and ice in the cooler regions.

Chaos and Current Structure00:02:20

Collisions between protoplanets and asteroid bombardments shaped the current solar system, resulting in the organized motion we observe today.

Scientific Standing00:02:57

While the Solar Nebula Theory is widely accepted and supported by evidence, scientists continue to refine the details of how individual planets developed.
