Meteor Shower The interplanetary space is full of stones, diameter of which makes tens meters and fewer. When these meteoroids rush into the Earth’s atmosphere with a relatively high speed, they leave the visible traces created by a strong heating caused by friction, which evaporates them. They are called meteors or "falling stars". Meteors enter into the Earth’s atmosphere on a regular basis. In normal night, it is usually possible to see some single meteors per hour. Nevertheless, in a certain time, the density of observed meteors is much higher. These periods are called meteor showers. The particles causing the emergence of a meteor represent an interesting class of astronomical objects. The names given to them actually change, depending on the place of their location. For example, during movement in a space, particles are called meteoroids. When they enter into Earth’s atmosphere, they are referred to as meteors. If their size is rather big to reach and hit the Earth’s ...
