SOLAR SYSTEM

Detailed explanation-1: -This concept is called the nebular hypothesis.

Detailed explanation-2: -The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].

Detailed explanation-3: -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-4: -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-5: -Jovian planets formed as gravity drew gas around ice-rich planetesimals much larger than Earth; (when it gets about 10 Earth masses) therefore they had a strong enough gravity that it could capture and hold hydrogen and helium that made up a vast majority of the material in the solar nebula.

Detailed explanation-6: -The big difference is that Terrestrial planets are mostly made of rock and even more dense material, while Jovian planets are mostly made of hydrogen and helium, which are less dense. The solar nebula theory explains that planets are formed by solid bits of matter.
