“A shooting star is a dying star that breaks away from the celestial vault and falls to Earth before going out. » This is what men thought a long time ago. Of course, our view of the Universe has changed considerably since ancient times and we now know that shooting stars are in fact mostly comet dust that enters and burns in the atmosphere due to their great speed. We can observe them every night, but special periods allow us to see a greater number of them. This is the case when the Earth crosses the wake of a comet, for example in August. From 20,000 to 40,000 tonnes of extraterrestrial matter weigh down the Earth each year. But as beliefs die hard, these phenomena have kept their name, which, it must be admitted, is very poetic.<end_of_turn><eos>
