The satellites are mainly two types, These are Natural satellites and Artificial satellites.the moon is the perfect example for natural satellite, is of the earth.The moon revolves to the Earth, the moon has been placed into the Orbit. Orbit is a Eclipse curved path for Planets, Satellites and any Objective with Gravitational force into the space. Solar system, Star system and Planets are throughing to be Orbit curve. In Space have three types of Orbits, they are Low Earth Orbit(LEO) and Medium Earth Orbit(MEO) and Geo Stationary or Geosynchronous Earth Orbits(GEO). The low earth orbit range is between 160km to 1,600km from above the earth and medium earth orbit range is between 10,000km - 20,000km above the earth and geostationary orbit range is 35,786km above the earth.Every Artificial satellites are works different specific job, so the Artificial satellites are depends on human requirements.The totally 8,300 satellites are around in the world. 3,000 satellites are expired and crashed. Every satellite has maximum 20 years operational life time.

The first Artificial satellite was sputnik-I. It was launched by the Soviet union of Russia on October 4 , 1957.The sputnik-1 used for recognize the density of high Atmospheric layers.The Sputnik-I went into the space without any passengers. It sent the data on Radio signal distribution in the Ionosphere and after One month the another Artificial satellite launched. It was sputnik-II.It launched on November 3 in the same year.
The Russian Soviet Union was made an experiment with Sputnik-II. The first passenger through away into the space track. The passenger was a dog. A dog named Laika.
Presently 55 countries launching the satellites in the world.The each country has it's own launching stations. Americans are famous for launching new satellites with Advanced develop features and Russia, India are also launching new satellites.
The satellites are semi-independent and contain Auto-programming for analyzing tasks.The satellites are automatic computer controlled systems.They generate the power in own way. The satellites work and depend on Solar power, the solar plates are on satellite wings for generate power .
The every satellites have launching vehicles(SLV), SLV are take satellite from the Earth into the space.The SLV's are also called as Rockets. From where the satellites launched are known as 'Launching stations'.
