Chamberlin’s Planetesimal Hypothesis
- The Planetesimal Hypothesis of Chamberlin, also known as the Binary Theory, was proposed by Chamberlin and Moulton in 1900.
- According to this theory, another wandering star collided with the sun. As a result of this collision, a cigar-shaped extension formed from the celestial material, and the surface of the sun separated from this extension.
- The sun emitted hot material called “Prominences,” which were very high in temperature.
- The particles from these materials began to spin and coalesce, forming the planets.
- This process generated a significant amount of heat.
- As the separated materials cooled down, they started to condense and form the planets.
- The passing star then moved away, and the sun continued to spin on its own axis.
- However, the Binary Theory fails to explain why only nine planets were formed during the collision of these stars.
Early Theories of the Earth| Class 11 Geography Notes
Early Theories of the Earth: The Earth and other planets in our solar system formed due to the pull of gravity. About 4.63 billion years ago, the solar system was a cloud of gas and dust called a “Nebula.” In this discussion, we’ll explore early theories about Earth’s origin, including Kant’s “Gaseous Hypothesis”, Laplace’s “Nebular Hypothesis” and also Chamberlin’s “Planetesimal Hypothesis” in this article. These notes are specially curated by an expert team at w3wiki for all the students for their better understanding and to help them in their examinations.
