As the solar nebula began to collapse, gravity caused it to shrink and spin faster. This led to the formation of a protostar at the center, while the outer material flattened into a spinning disk. Within this disk, dust and gas started to clump together and eventually formed planetesimals, which further accreted to form planets.
The solar nebula was a rotating cloud of gas and dust that formed our solar system about 4.6 billion years ago. It consisted mostly of hydrogen and helium, with traces of other elements. Over time, gravity caused the nebula to collapse and form the Sun and the planets.
The force of gravity caused the solar nebula to contract. As the nebula collapsed under its own gravity, it began to spin and flatten into a disk shape, eventually forming the Sun and the planets. Additionally, the heat and pressure generated by the gravitational contraction contributed to the collapse of the nebula.
Pressure and gravitymay have become unbalanced in thesolar nebula because of an externalforce such as a collision of the solarnebula with another nebula or from anearby exploding star. This type offorce, was strong enough to overcomethe pressure of the nebula and triggerits collapse.
The nebular model explains how our solar system formed from a rotating cloud of gas and dust called a solar nebula. Gravity caused the nebula to collapse, forming a central protostar surrounded by a spinning disk. Over time, the material in the disk clumped together to form planets and other solar system bodies.

One of the events that did not occur during the collapse of the solar nebula was the formation of the first stars in the universe. Instead, the collapse of the solar nebula led to the formation of our solar system.

Earth formed about 4.5 billion years ago from a cloud of gas and dust called the solar nebula. Gravity caused the nebula to collapse, forming the Sun at the center and the remaining material to clump together to form planets like Earth.

The Sun.
The solar system formed from a rotating cloud of gas and dust called the solar nebula about 4.6 billion years ago. Gravity caused this cloud to collapse and form the sun at its center, with the remaining material forming the planets, moons, asteroids, and other objects in the solar system.
The nebular hypothesis suggests that our solar system evolved from a huge rotating cloud of gas and dust called a solar nebula. Over time, gravity caused the nebula to collapse and spin faster, forming the sun at the center and the planets and other objects in orbit around it. This process is supported by evidence from observations of other star systems and the composition of our own solar system.

Inner planets
The nebular model explains how our solar system formed from a rotating cloud of gas and dust called a solar nebula. Gravity caused the nebula to collapse, forming a central protostar surrounded by a spinning disk. Over time, the material in the disk clumped together to form planets and other solar system bodies.
A solar nebula begins to form when a cloud of gas and dust in space collapses under its own gravity. This collapse can be triggered by a nearby supernova explosion, a shockwave from a passing star, or other disturbances in the interstellar medium.
