SOLAR SYSTEM

Detailed explanation-1: -The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets.

Detailed explanation-2: -most astronomers preferred the so-called collision theory, in which the planets were considered to have been formed as a result of a close approach to the Sun by some other star.

Detailed explanation-3: -The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud-the solar nebula. – (Nebula is the Latin word for cloud.) Kant and Laplace proposed the nebular hypothesis over two centuries ago. A large amount of evidence now supports this idea.

Detailed explanation-4: -According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust.

Detailed explanation-5: -solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart.

Detailed explanation-6: -The Encounter Theory proposed by Georges Leclerc and Comte de Buffon explains that the solar system formed as a result of a near collision between a passing star and the Sun. As the star passes near the Sun, the materials of both the Sun and the star were drawn out.
