Key Points

• Nebular Hypothesis:-
  • Nebular hypothesis of Solar System's origin:
    • The Nebular Hypothesis of the origin of the Solar System was given by Laplace in 1796.
    • Laplace imagined that the planets had condensed from the primitive solar atmosphere.
    • It was originally extended far beyond the limits of the present-day system.

  • The stages of formation are
    • ​There was a Nebula formed by interstellar dust and cloud.
    • The Nebula started to collapse and condense.
    • The nebula flattened into a disk called the Protoplanetary Disk.
    • The solar system started forming
