Called shooting star the luminous phenomenon that accompanies the entry into the atmosphere of an extraterrestrial body (meteor). This streak of light is caused by the vaporization of the body and ionization of air in its path. These phenomena are mainly due to compression of the atmosphere ahead of the supersonic body (not friction). The phenomenon occurs between 120 and 85 km altitude. A meteor that reaches the ground is called a meteorite, and more generally, the body could cause these phenomena are called meteoroids. Each year at the same time, the orbit of the Earth crosses the dust clouds left by comets. This causes meteor showers, or "rain" falling stars, which appear to come from a perspective effect from the same point in the sky. We call this imaginary radiant. Some shooting stars do not seem to come from the radiant, they are grains of dust from outside the cloud crossed, they are called sporadic. These periodic meteor rain wear a name derived from the constellation in which their radiant lies. Thus, the Perseids (visible in August) have their radiant in the constellation Perseus. The swarm of Leonids give rise to actual meteor showers. ? "Zenithal Hourly Rate" - The "Zenith Hourly Rate" is the maximum number of meteors an ideal observer could see if the radiant was at its zenith under a sky perfectly clear.
