Shooting star

Currently, it is proved that the shooting stars such as solids, as well as meteorites, they fall into Earth's atmosphere from outer space, and breaking into it with the escape velocity, begin to glow. Height, where they light up and die, different, one can assume that at the time of occurrence, they are within 15 miles of the earth's surface, and at the time of extinction - 11 miles. Light phenomena and in this case depend on the air that is compressed and warms up quickly flying across his body for reasons of extinction may be different: either the body breaks down into dust because of the high temperature, and perhaps even burns or goes again from within the Earth's atmosphere . In most cases, the stars are lonely at longer intervals, sometimes they are incredibly fast one after another. In 1799, 11 / 2 am on Nov. 12 in Kumano in Venezuela, Alexander Hum-bolt noticed on the eastern part of the whole firmament thousands of fireballs and shooting stars, all of whom flew in one direction, from north to south. Subsequently okazalod that such a stream of falling stars was seen across America from the equator to Greenland, and reached Germany. Area covered by them, stretched up to 1 million square meters. miles. At first, astronomers did not pay sufficient attention to this phenomenon, but it subsequently filed a common interest, it was soon proved that certain periods of the year and are characterized by well-known night then stronger, then weaker falling stars.
