Earth and the solar system
The formation of the Earth and the entire solar system goes back billions of years, when conditions were favorable for the formation of the Earth and the solar system. Planets are made of gas and dust clouds that orbit the new stars. The solar system in which we live consists of a medium-sized star known as the sun, in addition to eight planets revolving around the sun. The formation of the sun dates back 5 billion years, when a giant cloud floated in one of the spiral arms of the Milky Way galaxy, and this giant cloud consisted of gas and dust, and the largest formation of gases was hydrogen and helium gas, in addition to a few heavy gases. Astronomers called this cloud the nebula. After that, this cloud began to collapse, which led to the separation of atoms from each other, and the generation of a conflict between them, which resulted in the production of high heat, and with the increasing violent movement of the atoms, the temperature rose more and more, which led to the fusion of protons in the centers of the atoms, known as nuclear fusion. In this way the sun or the radiant star of the Milky Way was born.
The birth of planet Earth
At a certain distance from the sun, materials collided with each other to form planets. Where the planet Earth was also formed from the colliding materials together, and the formation of the Earth is completely different from the formation of the moon. Thus, the formation of the earth in space was like the formation of the rest of the planets in the galaxy, and it is through the collision of materials with each other that forms the planets. With all these collisions, the Earth's temperature rose, which led to the melting of rocks and minerals, which recently became part of the Earth's formation and crust; After it was divided into layers forming the Earth in its current form.

The solar system of the Milky Way contains eight planets: Mercury, Venus, Earth, Mars, Jupiter, and Saturn. Saturn), Uranus, and Neptune. Each of these planets is a certain distance from the sun, and therefore the planets were arranged according to their distance from the sun.
