The meteor showers are small dust particles cosmic deposited by a comet and, in its annual trip around the Sun, Earth encounter.
Dust particles entering the Earth's atmosphere and disintegrate rapidly, shining in his downfall. In the case of the Perseids, the particle cloud that is the Earth has been produced by the 'Swift-Tuttle', a comet discovered in 1862 and we visit every 120 years. The name 'Perseids' comes from the constellation in which it originated.
The area of the sky in which the traces appear to originate from a bright meteor shower is called "radiant". For this rainfall occurs radiant in the constellation Perseus, near the famous double cluster in Perseus and about halfway between this and the constellation Cassiopeia.
To observe the Perseids you should move away from urban areas and watch the illuminated sky from a comfortable position (preferably half lying down) and without any tool. We must look towards the north of the radiant that when the maximum is on the northeast horizon at a height of about 20 degrees.
