Gravity.
A solar nebula is a cloud of gas and dust in space that serves as the precursor to star and planet formation. About 4.6 billion years ago, our solar nebula collapsed under gravity, leading to the formation of the Sun at its center and the surrounding protoplanetary disk. Within this disk, particles collided and coalesced to form planetesimals, which eventually merged to create the planets, including Earth. Thus, the solar nebula is fundamental to understanding how Earth and the other planets in our solar system formed.
The celestial bodies of our solar system are believed to have formed from the solar nebula. The solar nebula was a giant cloud of dust and gas that was left behind after the formation of the sun.
The theory that explains the formation of planets through the condensing of a solar nebula is known as the Solar Nebula Theory. According to this theory, the solar system originated from a rotating cloud of gas and dust, known as the solar nebula. As the nebula collapsed under its gravity, it spun faster and flattened into a disk, allowing particles to collide and stick together, eventually forming larger bodies that became the planets. This process highlights the role of gravity and angular momentum in the formation of celestial bodies.
The three major components of the solar nebula are hydrogen, helium, and heavier elements or compounds. Hydrogen and helium account for the majority of the nebula's mass, while heavier elements, often referred to as "metals" in astrophysics, contribute to the formation of solid materials such as dust and ice. These components played a crucial role in the formation of the Sun and the planets in our solar system.
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.
If the solar nebula had no angular momentum initially, it would not have been able to form a spinning disk, which is necessary for the formation of a solar system. This spinning motion is what causes the material in the nebula to flatten into a disk shape, leading to the formation of planets and other celestial bodies. Without angular momentum, the material in the nebula would not have been able to come together to form a solar system as we know it.

A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.

The Nebula Theory is also known as the Solar Nebula Theory. It is a widely accepted model for the formation of our solar system.
In the formation of our solar system, nearly all the mass of the solar nebula became the Sun, which accounts for about 99.86% of the solar system's total mass. The remaining material formed the planets, moons, asteroids, and comets. This process involved the gravitational collapse of the nebula, leading to the Sun's formation at the center, while the residual matter coalesced into the various celestial bodies orbiting it.
