SOLAR SYSTEM

Detailed explanation-1: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula.

Detailed explanation-2: -Currently the best theory is the Nebular Theory . This states that the solar system developed out of an interstellar cloud of dust and gas, called a nebula .

Detailed explanation-3: -Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.

Detailed explanation-4: -Before it was moulded into a neat set of planets, every scrap of matter in the solar system was part of a gigantic nebula-a floating interstellar cloud. This giant cloud was made up of dust, hydrogen, and other gases. It began to collapse in on itself after becoming gravitationally unstable.

Detailed explanation-5: -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].
