Solar System

The solar system is a system consisting of a group of stars, planets and other objects that are connected to each other under the sun's orbit This system contains the sun and the nine planets. The Earth is one of these planets. Earth is the only planet that can Living organisms, although there are some institutions looking in this area believe that there are many space objects in the other planets, and man because of the development of technology to reach the other planets, and the Moon for a limited time

How the solar system formed
The solar system was a cloud containing a group of gas and dust known as the nebula, which lies deep within the spiral arm of the Milky Way galaxy. This cloud contained hydrogen, light helium, low oxygen, And the iron, the nebula at that time was slow as it circled around its center; it contained blocks of intricate vortexes that had been swirled by the polarization, and by the influence of gravitational forces, one of the four major powers, the nebula took its course in the shape of a  rotary disk, Follow him Increasing its temperature, and its density in its center, which ended with the formation of the sun

The outer part of this cloud, which was cold and large in size, contained substances such as water, ammonia and methane, which were hardened like snow in a low density environment. Materials near the sun such as silicon, iron and aluminum combined with oxygen, Crystallized into solid materials and rocky materials under high temperature. These materials did not combine with other glaciers on the edges of the cloud. Silicates were found in the middle, and after a relatively short time, less than 100,000 years. After the nebula

The immature in this system is a knock These planets were made up of primitive rocks and ice, and these planets grow and grow thanks to the magnificence of gravity as they rotate in their orbits around the sun, This is done by capturing small objects nearby, until they become major planets. The size and components of the planets depend on their distance or proximity

The planets whose orbit is close to the sun are characterized by a high temperature, and the metals, silks and collars are formed to form these planets. The planets with distant orbits of the sun are characterized by low and cold temperatures. Water, methane and nitrogen become Such as ice and coalescing around each other to form these planets. These materials are characterized by rapid evaporation and thus abundant, which means that their sizes are larger; they are located in distant of the solar system

There are two planets: the inner planets that contain our planet Earth, Mercury, Venus, Mars, and outer planets far from the Sun are Jupiter, Saturn, Uranus, Neptune, and Pluto
