Which theory describes the formation of the solar system from a huge cloud of dust and gases?

Answer 1

Summary:

The Kant Nebular Hypothesis

From wikipedia:

"There is evidence that the nebular hypothesis was first proposed in 1734 by Emanuel Swedenborg.[1][2] Immanuel Kant, who was familiar with Swedenborg's work, developed the theory further in 1755.[4] He argued that gaseous clouds-nebulae, which slowly rotate, gradually collapse and flatten due to gravity and eventually form stars and planets. A similar model was proposed in 1796 by Pierre-Simon Laplace.[4] It featured a contracting and cooling protosolar cloud-the protosolar nebula. As the nebula contracted, it flattened and shed rings of material, which later collapsed into the planets.[4] While the Laplacian nebular model dominated in the 19th century, it encountered a number of difficulties. The main problem was angular momentum distribution between the Sun and planets. The planets have 99% of the angular momentum, and this fact could not be explained by the nebular model.[4] As a result this theory of planet formation was largely abandoned at the beginning of the 20th century."

Edit : As far as I know, the modern theory of how the Solar System was formed

is based on modified version of the "Nebular Hypothesis".

So it's not been abandoned after all.

Note: But the Laplacian model of it has, as the wikipedia article states.

Answer 2

No, It Was A Rotating NEBULA Of Just Dust.

Comment: I'm pretty sure there's supposed to have been gas too.

Answer 3

A huge quantity of dust and gases are still present in space which are the basic material to form the planets.

Answer 4

Accretion theory

Answer 5

The dust cloud or ( nebula ) theory
