Imagine walking along a mountain path. At some point you are near a junction with another path, and while you decide to go through here is that a motocross bike through there at full speed ahead, raising a great cloud of dust and bringing you some snot and hope to finish a tree . Here
with tears of St. Lawrence a little bit the same thing happens. There is a meteor that crosses the path of the earth around the sun, the comet Swift Tuttle. Does not relieve itself from the gravel path, but we say that losing pieces in the street. Many, small, and little cares ... has a good supply. The land avoids confrontation, but turning around the earth passing by once a year, on time, in the same period, which for convenience we call August 10 (although in reality the point of impact is broad and the land it crosses over several days). These pebbles
lost by the comet if they float placidly throughout the path of the comet, including stops at the point where every year the earth moves. And when she passes, here they seem to scratch as fire arrows at the sky. In reality it is we who go to them. And when the battle is with our atmosphere at 59 km per second, the impact is such that crumble, so much so that it does not fall to the ground next to nothing.
This "swarm" of "shooting stars" who obviously are neither star nor falling, it is not the only one to hit the ground, but it is certainly the most popular and eye-catching, also because it happens in summer. The Leonids dippers would be as flashy, but the peak of visibility November 16, when the cold over there that remove the clouds poetry event. These are called Perseadi of August, because the point "radial" in which you join all the trails of meteors is very near the constellation Perseus. A bit like the hub of a bicycle wheel, where all races meet.
Well, the end of the lesson. You just have to look at them.
