 The solar system 

The solar system is called the set of stars and celestial matter that gravitates in an orderly manner around the sun. There are several solar systems in the universities, but normally we refer to our solar system, located in the galaxy known as the Milky Way.  Receive the solar system number because the central center of rotation is determined by the sun. The sun attracts the group of planets, dust, matter, radiation and magnetic fields from the sun.  In our solar system there are eight planets, which trace elliptical orbits. Following the order of proximity to the sun, the planets of the solar system are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Uranus.  The solar system is only a small part of the universe. Planets and asteroids rotate in elliptical orbits around the sun. The sun is a star made of burning plasma, with a diameter of 696,000 kilometers.

The earth

Earth is the third planet in the solar system according to its proximity to the Sun and the only star known to have life. 29% of its surface is covered by land in the form of continents and islands and 71% by water, most of which is found in the seas and oceans, which form the hydrosphere together with lakes, rivers and other freshwater bodies. Much of the polar region is covered in ice. The outer layer of the Earth is divided into numerous rigid tectonic plates that move across the surface over periods of many millions of years. Its interior remains active, with a solid inner core, a liquid outer core that generates the Earth's magnetic field, and a convective mantle that feeds the phenomenon of plate tectonics.
