Sun and Planets makes Solar System

Solar System consists of the Sun and small celestial bodies. The first Planet to the Sun is Mercury and further order is Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and "Pluto". The system consists of the 150 natural satellite (circling the Planets). Also, many small bodies such as comets, planetoids, bodies of Kuiper belt, meteoroids and interplanetary dust.

The entire system gathers common gravitational force and the physical condition is determined with the solar energy radiation. Solar plasma fills the heliosphere. Gravitational influence spreads to areas of the comets Oort cloud. Cloud is closer than neighboring stars. The Planets were divided into two groups. First group is internal, where the Earth and it's similar three Planets Mercury, Venus and Mars. Second group is external, with Jupiter and it's similar giant Planets Saturn, Uranus and Neptune. Internal is a group of rocky, with a thin atmospheric layer, without which is only Mercury. The outer Planets are gaseous with small rocky core. Their composition is closer to the composition of protoplanetary cloud from which the Planets formed.

The chemical composition of Jupiter is almost identical to the Sun. The difference between these two groups is a result of development in which the radiation of the young Sun warmed the core of closer Planets and cleanse them from easily volatile elements, thus forming a solid surface and there are geological processes developed secondary predominant atmosphere of carbon dioxide (Venus and Mars) and tertiary Earth's atmosphere from nitrogen and oxygen.

Kuiper Belt is located between Neptune and Pluto. It has a smaller celestial bodies. Most asteroids composed mainly of rock and metal. Most of the Kuiper Belt objects built of frozen volatiles. That is also called "ice". Such as methane, ammonia and water. Assumed Oort Cloud is a huge spherical cloud of cometary nuclei that forms the border of the Solar System, a thousand times farther from the Kuiper Belt.
 

Solar System is created from interstellar cloud

Solar system was created originally from Nebula or interstellar clouds. It was filled with gas, dust and ice grains. That cloud is in the midst of collapsing gravity began to spin and tied up in a round disc in which Planets are beginning to grow. Bits of dust and ice, circling around the young Sun, colliding and merging, were becoming larger and so shaped the Earth. In the fierce mutual collisions of these huge building blocks were created and other Planets. The Planets orbit the Sun and orbits in our Solar System is elliptical. In space, there are many different systems like ours. In some, Planet the size of Jupiter orbiting next to the Sun and it is assumed that it is possible that Jupiter also circling our Sun and later flew to many distant orbit around the Sun.
