Astronomy:planets in the solar system

Planets of the solar system is a system of planets centered on a bright star, a source of energy, heat and light - the Sun.

According to one theory the Sun was formed along with the Solar system about 4.5 billion years ago in the explosion of one or more supernovae. Initially the Solar system was a cloud of gas and dust particles that are in motion and under the influence of its mass formed a disk where there was a new star, the Sun and our entire Solar system.

In the center of the Solar system is the Sun, around which revolve in the orbits of the nine major planets. As the Sun shifted from the center of planetary orbits, the cycle of revolution around the Sun planets that close, we are moving away in their orbits.

The universe is incredibly vast place, so incredible that even the human imagination cannot span the entire depth of the vastness of the Universe. As for our Solar system, by the standards of the Universe it is only a tiny part of it. While for us mere mortals of the inhabitants of a small planet called Earth - a planet in the sky, the Solar system is a very big place, and despite all the great achievements of astronomy in recent years, much remains unknown, we only studied the planet for children to get closer to the borders of his native Solar system.
